Question

What is the solution if the inequality shown below? a+2<-10​

Answer 1

`\huge \boxed{a<-12}\checkmark`

Explanation:

Subtract by 2 both sides of equation.

`\displaystyle a+2-2<-10-2`

Simplify, to find the answer.

`-10-2=-12`

`\displaystyle a<-12`, which is our answer.

Answer 2

a < -12

Explanation:

Isolate the variable, a. Treat the < as a equal sign, what you do to one side, you do to the other. Subtract 2 from both sides:

a + 2 < -10

a + 2 (-2) < -10 (-2)

Simplify:

a < -10 - 2

a < -12

a < -12 is your answer.
