Question

A−15=4a−3 solve for a

Answer 1

Answer:

a = -4

Step-by-step explanation:

To solve for 'a', isolate 'a'.

      a - 15 = 4a - 3

Subtract '4a' from both sides,

a - 4a  -15 = -3

Combine like terms,

     -3a - 15 = -3

Add 15 to both sides,

        -3a = -3 + 15

         -3a = 12

Divide both sides by (-3),

            a = 12 ÷ (-3)

           $\sf \boxed{\bf a = (-4)}$
