Y+6x=11; 3x+2y=-2 6x + y + - 6x = 11 + - 6x (Add - 6x to both sides)
y = - 6x + 11
Substitute - 6x + 11 foryin 3x + 2y = - 2
3x + 2y = - 2
3x + 2 ( - 6x + 11) = - 2
- 9x + 22 = - 2 (Simplify both sides of the equation)
- 9x + 22 + - 22 = - 2 + - 22 (Add - 22 to both sides)
- 9x = - 24
- 9x / - 9 = - 24 / - 9 (Divide both sides by - 9)
x = 8 / 3
