Question

Y=-4x - 8

6x + 2y=-10


I need the equation solved by substitution

Please show work :)

Answer 1

x =1.28571428571

Explanation:

6x + 2y = -10

y = -4x - 8

6x + 2(4x - 8) = -10

6x + 8x - 8 = -10

14x - 8 = 10

(we put together the like terms)

14x = 10 + 8

14x = 18

x =
`(18)/(14)`

x = 1.28571428571
