Chapter 4 - Section 4.2 - Solving Systems of Linear Equations by Substitution - Exercise Set: 18

Answer

No solution

Work Step by Step

1. Solve the first equation for y: 2y = x + 2 y = $\frac{x + 2}{2}$ 2. Substitute the solution for y into the second equation: 6x - 12($\frac{x + 2}{2}$) = 0 3. Solve for x: 6x - 6(x + 2) = 0 6x - 6x - 12 = 0 -12 = 0 The equation is false, so there is no solution to the system of equations.
