Question

Solving systems of equations by elimination

Answer 1

x = -1 and y = -2

Explanation:

use elimination or subatitution method

Answer 2

`\boxed{x = -1~~and~~ y =-2}`

Explanation:

-6x + y = 4

6x - 2y = -2 +

-y = 2

y = -2

.

Substitute the value of y to the one of equations

6x - 2y = -2

6x -2(-2) = -2

6x + 4 = -2

6x = -2 - 4

6x = -6

`x = (-6)/(6)`

x = -1
