Solve: За – 6 = -12 a =​

a=−2

Step-by-step explanation:

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

3a−6=−12

Step 1: Add 6 to both sides.

3a−6+6=−12+6

3a=−6

Step 2: Divide both sides by 3.

3a /3 = −6 /3

a=−2

a= 2/5 or 0.4

Step-by-step explanation:

3a−6=−12a

Step 1: Add 12a to both sides.

3a−6+12a=−12a+12a

15a−6=0

Step 2: Add 6 to both sides.

15a−6+6=0+6

15a=6

Step 3: Divide both sides by 15.

15a/15=6/15

a=2/5
