Solve the following system of equations. What is the x-value of the solution?

3x + 2y = 7

x - y + 1 = 0

x = 1

Step-by-step explanation:

Step 1: Choose one of the equations to solve for y:

x - y + 1 = 0

(-y) / - 1 = (-1 - x) / - 1

y = 1 + x

Step 2: Plug in y into either equation

3x + 2 (1 + x) = 7

3x + 2 + 2x - 2 = 7 - 2

5x / 5 = 5 / 5

x = 1

Answer: x = 1
