1 |
Problem |
Solve the equation: |
|
2 |
Hint |
Adding "+7" on both sides we get |
\$ 3\sqrt(x+9) - \cancel7 + \cancel7 = 12 + 7 \$ |
3 |
Step |
After cancellation we get |
\$ 3\sqrt(x+9) = 19 \$ |
4 |
Step |
Dividing on both sides by 3 we get |
\$ \cancel(3)/\cancel3 \sqrt(x+9) = 19/3 \$ |
5 |
Step |
After cancellation we get |
\$ \sqrt(x+9) = 19/3 \$ |
6 |
Step |
Squaring on both sides we get |
\$ (\sqrt(x + 9))^2 = (19/3)^2 \$ |
7 |
Step |
After cancellation we get |
\$ x + 9 = 361/9 \$ |
8 |
Hint |
Adding "-9" on both sides we get |
\$ x + \cancel9 - \cancel9 = 361/9 - 9 \$ |
9 |
Step |
After cancellation we get |
\$ x = (361 - 81)/9 = 280/9 \$ |
