Question

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

Answer 1

x = 7

Explanation:

8+4 = 2(x-1) (distribute the 2 to the x and -1)

8+4 = 2x -2 (collect like terms)

12 = 2x - 2 (add 2 on both sides)

14 = 2x (divide by 2 to get the x by itself)

7 = x

Hope this helps ya!!

Answer 2

x = 7

Explanation:

8 + 4 = 2(x - 1)

~Combine like terms

12 = 2(x - 1)

~Distribute right side

12 = 2x - 2

~Add 2 to both sides

14 = 2x

~Divide 2 to both sides

7 = x

Best of Luck!
