3x=y . Swap sides so that all variable terms are on the left hand side. \frac{3x}{3}=\frac{y}{3} Divide both sides by 3. x=\frac{y}{3} Dividing by 3 undoes the multiplication by 3. Examples. Quadratic equation { x } ^ { 2 } - 4 x - 5 = 0. Trigonometry. 4 \sin \theta \cos \theta = 2 \sin \theta. Linear equation. y = 3x + 4.
Problem: Solve 5x - 6 = 3x - 8. Calculator Solution: Move 6 to the right side—> 5x = 3x - 2; Move 3x to the left side—> 2x = -2; Divide both sides by -2—> x = -1; Benefits of Using an Algebra Calculator. Saves Time: Resolves complex problems. Enhances Learning: Steps that are specific help people understand.
1.1 Solve y-3x = 0 Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK). "y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis. In this formula : y tells us how far up the line goes
Graph y = 3x. Solution We can substitute 0 for x and find y = 3(0) = 0 Similarly, substituting 0 for y, we get ... (2, 3) and has a slope of 2. If we denote any other point on the line as P(x, y) (See Figure 7.1 la), by the slope formula. Thus, Equation (1) is the equation of the line that goes through the point (2, 3) and has a slope of 2. ...

Find the Slope and y-intercept y=3x+4. Step 1. The slope-intercept form is , where is the slope and is the y-intercept. Step 2. Find the values of and using the form . Step 3. The slope of the line is the value of , and the y-intercept is the value of . Slope: y-intercept: Step 4
In conclusion, x is expressed as y−13 in the formula y=3x+1. This formulation allows us to calculate the value of x based on a given value of y, thereby rearranging the original equation to solve for x in terms of y. The formula x=y−1/3 serves as a clear expression of x in terms of y, providing a systematic way to compute x based on ...

Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x; When x is 0, y is already 1. So +1 is also needed; And so: y = 2x + 1; Here are some example values:

Step 2: Plug One point and Slope, m, into the Slope-Intercept Form Formula (y=mx+b) Now we can write the equation of the line in slope-intercept form where m=-1 as follows: y = -1x + b. y= -x + b. Now, let’s take one of the two given points and plug it into the slope-intercept form equation to solve for b as follows:

If you substitute y = 7 into the equation x = 3 y − 1 , you would calculate x = 3 7 − 1 = 3 6 = 2, showing how to find x from a given y. This method of solving for a variable in terms of others is a fundamental principle of algebra, which maintains equality through valid operations such as addition, subtraction, multiplication, and division.
