1 |
Problem |
Given that: |
|
2 |
Hint |
After simplification |
\$ (3(x + 6))/2 = (2(x - 3))/3 \$ |
3 |
Step |
After multiplication |
\$ (3x + 18)/2 = (2x - 6)/3 \$ |
4 |
Step |
Multiply both sides on \$'2\times3'\$ |
\$ (3x + 18)/\cancel(2) \times \cancel(2)\times 3 = (2x - 6)/\cancel(3) \times cancel(3) \times 2 \$ |
5 |
Step |
After simplification |
\$ 3(3x + 18) = 2(2x - 6) \$ |
6 |
Step |
After cancellation |
\$ 9x + 54 = 4x - 12\$ |
7 |
Step |
Substract both sides on 4x |
\$ 9x - 4x + 54 = \cancel(4x) - \cancel(4x) - 12 \$ |
8 |
Step |
After cancellation |
\$5x + 54 = -12 \$ |
9 |
Step |
Substract both sides on 54 |
\$ 5x + \cancel(54) - \cancel(54) = -12 - 54\$ |
10 |
Step |
After cancellation |
\$ 5x = -66\$ |
11 |
Step |
Divide both sides on 5 |
\$ (\cancel(5)x)/\cancel(5) = -66/5 \$ |
12 |
Step |
\$ x = -66/5\$ |
