3x + 3y = 9 3(0) + 3y = 9 y 2 = 3 x 2 = 0. Get Graph Plot Coordinates Getting two graph points will allow you to make a straight line on a graph. The plot coordinate format is (x 1,y 1) and (x 2,y 2). Thus, we use the x-intercept and y-intercept results above to get the graph plots for 3x + 3y = 9 as follows:
Transcript. Ex 3.2, 1 Solve the following pair of linear equations by the substitution method. (iii) 3x – y = 3 9x – 3y = 9 3x – y = 3 9x – 3y = 9 Solving (1) 3x – y = 3 3x = y + 3 x = (𝒚 + 𝟑)/𝟑 Putting value of x in (2) 9x – 3y = 9 9((𝑦 + 3)/3)−3𝑦=9 3(y + 3) – 3y = 9 3y + 9 – 3y = 9 3y – 3y + 9 = 9 0 + 9 = 9 9 = 9 The statement is true for all values of x So ...
by plugging the function (y = 3x + 15) into the y value in the function (3x + 3y = 9), you can then solve to find that x = -3. After solving for the x-value, plug -3 into the easiest equation to solve for the y-value (y = 3x + 15) to then find that y = 6. This is method of solving is called substitution
Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 A. Subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. B) Substitute the value of x in the first equation (x + y = -2) to get y = 1. C) The solution for the system of equations is (-3, 1).

To find the x-intercept (s), substitute in for and solve for .. Step 1.2. Solve the equation.
9x - 3y = 9 ...(2) From (1), we obtain. y = 3x - 3 ...(3) Substituting this value in equation (2), we obtain. 9x - 3(3x - 3) = 9. 9x - 9x + 9 = 9. 9 = 9. This is always true. Hence, the given pair of equations has infinite possible solutions and the relation between these variables can be given by y = 3x - 3.
3x-9=-3y . Swap sides so that all variable terms are on the left hand side. 3x=-3y+9 . Add 9 to both sides. 3x=9-3y . The equation is in standard form. \frac{3x}{3}=\frac{9-3y}{3} Divide both sides by 3. x=\frac{9-3y}{3} Dividing by 3 undoes the multiplication by 3. x=3-y . Divide -3y+9 by 3.
