Question

What is the value of x in the equation 8x – 2y = 48, when y = 4?

Answer 1

Answer:

x=7

Step-by-step explanation:

8x – 2y = 48

Let y=4

8x - 2(4) = 48

8x - 8 = 48

Add 8 to each side

8x -8+8 = 48+8

8x = 56

Divide each side by 8

8x/8 = 56/8

x = 7

Answer 2

Answer:

x = 7

Step-by-step explanation:

since we know y = 4, we can plug this into the equation to find x

8x - 2y = 48

8x - 2(4) = 48

8x - 8 = 48

8x = 56

x = 7
