Problem |
Given that: |
|
2 |
Hint |
Multiply both sides on (3x + 10)(x - 3) |
\$ 4/\cancel((3x + 10)) \times \cancel((3x + 10))(x - 3) = 2/\cancel((x - 3)) \times (3x + 10)\cancel((x - 3)) \$ |
3 |
Step |
After cancellation |
\$ 4(x - 3) = 2(3x + 10) \$ |
4 |
Step |
After multiplication |
\$ 4x - 12 = 6x + 20 \$ |
5 |
Step |
Add both sides on 12 |
\$ 4x - \cancel(12) + \cancel(12) = 6x + 20 + 12 \$ |
6 |
Step |
After cancellation |
\$4x = 6x + 32 \$ |
7 |
Step |
Substract both sides on 6x |
\$ 4x - 6x = \cancel(6x) - \cancel(6x) + 32 \$ |
8 |
Step |
After cancellation |
\$-2x = 32 \$ |
9 |
Step |
Divide on both sides 2 |
\$ (-\cancel(2)x)/\cancel(2) = \cancel(32)^16/\cancel(2)^1 \$ |
10 |
Step |
After cancellation |
\$ x = -16 \$ |
