Question

Solve the inequality for w.
w+7<20
Simplify your answer as much as possible.
0

Answer 1

w < 1`3

Explanation:

Isolate the variable w on one side of the inequality sign.

w+7<20

w<20 - 7

w<13.

Answer 2

w<13

Explanation:

Works identically to a normal single-variable equation.
Subtract 7 on both sides in order to isolate w--->w+7-7<20-7
The answer (which cannot be simplified any further) is w<13.
