13 points ! solve each equation or inequality. (show your work) first problem: n/4 + 2 = -9 second problem: 3/4x = -12

First problem:

n/4 + 2 = -9

        -2      -2

n/4 = -11

x4       x4

n = -44

Check:

-44/4 + 2 = -9

-11 + 2 = -9

-9 = -9

Second problem:

3/4x = -12

0.75x = -12

0.75       0.75

x = -16

3/4 * (-16) = -12 OR 0.75 * (-16) = -12

-12 = -12

Still get the same answer.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
