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)
