Question

How many solutions exist for the given equation?

1/2(x + 12) = 4x - 1

Answer 1

1 solution.

Explanation:

1/2(x + 12) = 4x - 1

Expand the brackets.

1/2x + 6 = 4x - 1

Subtract 6 and 4x and both sides.

1/2x - 4x = -1 - 6

-7/2x = -7

Multiply -7/2 on both sides.

x = -7 × -2/7

x = 14/7

x = 2
