5x -12 = -32
Group of answer choices

x = 5

x = 4

x = -4

x = -4

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Note that: PEMDAS =

Parenthesis

& is the order of operation.

In this case:

First, add 12 to both sides:

5x - 12 (+12) = -32 (+12)

5x = -32 + 12

5x = -20

Next, isolate the variable, x, by dividing 5 from both sides:

(5x)/5 = (-20)/5

x = -20/5

x = -4

x = -4 is your answer.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
