Problem |
Solve for y in the equation 3(x - 2) - 7y = 5 + y. |
|
2 |
Step |
The given equation is |
3(x - 2) - 7y = 5 + y |
3 |
Step |
Let’s start by distributing the terms |
3x - 6 -7y = 5 + y |
4 |
Step |
Move y term to right side and constant to left side |
3x - 6 - 5 = y + 7y |
5 |
Step |
After simplify |
3x - 11 = 8y |
6 |
Step |
Then slove for y |
\$y = (3x -11) /8\$ |
7 |
Solution |
So, the solution for y is \$y = (3x -11) /8\$. |

11 |
Choice-C |
This is wrong because it does not match the solution |
Wrong \$(3x + 8)/11\$ |
12 |
