Question

Solve for x. 13+15+18+x / 4 < 21

Answer 1

x < - 176

Explanation:

Order of operations rules require that we do division before addition. To remove the fraction, multiply all terms by 4:

4(13 + 13 + 18) + x < 84, or

4(44) + x < 84

Subtracting 4(44) from both sides, we get:

x < - 176
