What is the value of x in the equation 8x - 2y = 48, when y = 4?
6, 7, 14, 48

Solution:

Given 8x - 2y = 48 and y = 4

Solve the equation for given y.

Substitute y = 4 in the given equation

We get, 8x - 2(4) = 48

8x - 8 = 48

8x = 48 + 8

8x = 56

x = 56/8 = 7

x = 7

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

Summary:

The value of x in the equation 8x - 2y = 48, when y = 4 is 7.
