Solve by using any method of substitution

4 +8x = y
6x - y = 2

(-3,-20)

Step-by-step explanation:

4 +8x = y equation (1)

6x - y = 2 equation(2)

from equation 2

6x - y = 2

6x -(4+8x) =2

6x - 4 + 8x = 2

    +4              +4

6x - 8x = 6

-2x=6

divide by -2

x= -3

put x in equation (1) to solve for y

4 + 8x = y

4+8(-3)=y

4-24=y

-20=y

y= -20

solution = (-3,-20)
