Question

Which is the solution of b + 7 > -2 ?

Answer 1

b > -14

Explanation:

think of this as a normal equation:

b + 7 > -2

subtract 7 from both sides

b > -7 -7

b > -14

for future reference, when dividing an inequality by a negative number the sign also flips: for example,

-2x > 12

divide both sides by -2 to isolate x:

x < -6
