Hello!

WORK SHOWN BELOW

8x - 2y = 48, y =4

8x - 2(4) = 48

8x - 8 = 48

8x = 48+8

8x = 56

x = 56/8 = 7

x = 7

Answer:

x = 7

Step-by-step explanation:

Substitute y = 4 into the equation and solve for x

8x - (2 × 4) = 48

8x - 8 = 48 ( add 8 to both sides )

8x = 56 ( divide both sides by 8 )

x = 7
