Problem |
Solve for y in the equation \$ y + 2x + 11 = - y/3 + 2x \$. |
|
2 |
Step |
The given equation |
\$ y + 2x + 11 = - y/3 + 2x \$ |
3 |
Step |
Move all terms involving y to one side of the equation: |
\$ y + y/3 = 2x - 2x - 11\$ |
4 |
Step |
Combine like terms: |
\$ (3y + y)/3 = - 11\$ \$ (4y)/3 = - 11\$ |
5 |
Step |
Multiply both sides by \$3/4\$ to isolate y: |
\$ (4y)/3 times 3/4 = - 11 times 3/4 \$ \$ y = - 33/4 \$ |
6 |
Solution |
So, the solution for y is \$ y = - 33/4 \$. |
