With way one, we can easily count the tally marks, but with way 2 it becomes much harder for us to count the tallies when we are done.
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
<u><em>a=7</em></u>
