Question

3/a (-2) - 4 = 20 please help me out

Answer 1

Answer:

`\sf \large \: a = ( - 1)/(4)`

Explanation:

Let's solve your equation step-by-step.

3/a(−2)−4=20

−4a−6/a=20

Step 1: Multiply both sides by a.

−4a−6=20a

−4a−6−20a=20a−20a(Subtract 20a from both sides)

−24a−6=0

−24a−6+6=0+6(Add 6 to both sides)

−24a=6

−24a/−24=6/−24

(Divide both sides by -24)

a=−1/4
