Just try using each word in the sentence, and choose the one that makes the most sense!
1) B - Approximately.
2) D - Strength.

3x + 7 = x - 15
First, make sure to subtract

from both sides.
Second, simplify 3x - x to get 2x, and then keep the 7.
Third, subtract

Sixth, since 11 goes into 2 to get 22, simplify the fraction to 11.

Answer:
x = -11
