Question

What is the value of x in the equation 8 + 4 = 2(x - 1)?

a. 7
b. 5
c. 11/2
d. 13/2​

Answer 1

A. 7

Explanation:

We already know that 8+4 = 12, So now we have to find out how to make the equation equal 12.

2×6= 12, we have to find out what x will be in order to make the equation true.

2(7-1) = 2(6) = 12. Substitute the 7 for x.

x = 7
