Question

Solve for a show your work -2(a-3)=12

Answer 1

Answer:

a = -3

Step-by-step explanation:

-2(a-3)=12

distribute the -2 to the terms in the paranthesis

-2a + 6 = 12

minus 6 both sides

-2a = 6

divide -2 both sides to isolate a

a = -3

Answer 2

Answer: a=-3

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

  -2*(a-3)-(12)=0

(0 -  2 • (a - 3)) -  12  = 0

Pull out like factors :

  -2a - 6  =   -2 • (a + 3)

-2   =  0

A a non-zero constant never equals zero.

Solve  :    a+3 = 0  

Subtract  3  from both sides of the equation :  

                     a = -3
