Problem |
Given that: |
|
2 |
Hint |
Add both sides on 50 |
\$ 15a - \cancel(50) + \cancel(50) = 13a - 60 + 50 \$ |
3 |
Step |
After simplification |
\$ 15a = 13a - 10 \$ |
4 |
Step |
Substract both sides on 13a |
\$ 15a - 13a = \cancel(13a) - \cancel(13a) - 10 \$ |
5 |
Step |
After cancellation |
\$2a = -10\$ |
6 |
Step |
Divide both sides on 2 |
\$ (\cancel(2)a)/\cancel2 = -\cancel(10)^5/\cancel(2)^1 \$ |
7 |
Step |
After cancellation |
\$a = -5 \$ |
