Question

Simplify: 5(x − 4) − 3(x − 4) + 7(x − 4)

Answer 1

5(x − 4) −3(x − 4) +7(x − 4)

Since (x − 4) is common to all terms, we factor it out

[5 − 3 + 7] (x − 4)

Simplify 5 − 3 + 7

5 − 3 + 7 = 9

9(x − 4)

Expand 9(x − 4)

9(x − 4) = 9x − 36

The simplified expression is:

9(x − 4) or 9x − 36
