Example #2: Solve the following system using the substitution method 3x + y = 10-4x − 2y = 2 Step 1 You have two equations. Pick either the first equation (top) or the second equation (bottom) and solve for either x or y. I have decided to choose the equation on top (3x + y = 10) and I will solve for y. 3x + y = 10 Subtract 3x from both sides 3x − 3x + y = 10 − 3x y = 10 − 3x Step 2 ...

To solve a system of two linear equations using the substitution method: 1. From one equation, isolate a variable (e.g., \( x = \frac{c - by}{a} \)) 2. Substitute that expression into the second equation 3. Solve for the remaining variable 4. Use that value to solve for the first variable

Here are some more examples of using substitution to solve simultaneous equations: 3x + y = 13 5x-2y = 7 The coefficient of y in Equation 1 is 1. So first we make y the ... substitute this expression for x in Equation 2 and solve for y:-4(5 + 2y) + 5y = -26-20 - 8y + 5y = -26-3y = -6 y = 2 Finally, substitute the solution for y into the ...
