Question

Solve the system of equations using the substitution method.

x - 2y = -2
-4x + 3y = -5

Answer 1

So do we solve both of them, or just one of them I’m confused.

Answer 2

Answer:

x=16/5, y=13/5

Step-by-step explanation:

1. Multiply by 4 on the first equation and get a new equation: 4x-8y=-8
2. Plus the new and second equation: 4x-8y+(-4x+3y)=-8+(-5), and got -5y=-13, so y=13/5
3. After getting y=13/5, substitute in the first equation, x-2*(13/5)=-5, and got x=16/5
