Question

Solve the system of equations.

Answer 1

Explanation:

Step 1: Substitute x from the second equation into the second one

`2x - 9y = 14`

`2(-6y + 7) - 9y = 14`

`(2 * -6y) + (2 * 7) - 9y = 14`

`-12y + 14 - 9y = 14`

`-21y +14 - 14 = 14 - 14`

`-21y/-21 = 0 / -21`

`y = 0`

Step 2: Substitute y into the second equation

`x = -6y + 7`

`x = -6(0) + 7`

`x = 0 + 7`

`x = 7`

Answer:
`x = 7, y = 0`
