Question

Solve.
a-5/a+4=5/4

a = 0
a = -1
a = -9
a = -40

Answer 1

Step 1. Cross Multiply:
(a−5)*(4)=5*(a+4)
4a−20=5a+20

Answer 2

thank you

Answer 3

Step 2. Subtract 5a from both sides.
4a−20−5a=5a+20−5a
−a−20=20

Answer 4

Step 3: Add 20 to both sides.
−a−20+20=20+20
−a=40

Answer 5

Step 4: Divide both sides by -1
-a/-1 = 40/-1
a=−40
