Question

. For what value of x do the expressions 2x +2 and 3x – 6 have the same value?

Answer 1

x = 8

Explanation:

To find the solution, equate the 2 expressions, that is

3x - 6 = 2x + 2 ( subtract 2x from both sides )

x - 6 = 2 ( add 6 to both sides )

x = 8

As a check

2x + 2 = 2(8) + 2 = 16 + 2 = 18

3x - 6 = 3(8) - 6 = 24 - 6 = 18

Both expressions have the same value when x = 8
