-3a = -23+2
-3a = -21
a = 7


Place the -2 beside the -23. When you switch sides the negative will change to positive. Then there will be -3a on one side. After you do -23+2 the answer will be -21. -21 divided by -3a will make a = 7

Answer:

Step 1: Simplify both sides of the equation.

−2−3a=−23

−2+−3a=−23

−3a−2=−23

Step 2: Add 2 to both sides.

−3a−2+2=−23+2

−3a=−21

Step 3: Divide both sides by -3.

−3a−3=−21−3

a=7
