Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Steps | Problem | Solution |
|---|---|---|
1 |
Solve |
\$ 3(y/4 - 5)= -(y - 25) \$ |
2 |
After simplification |
\$ (3y)/4 - 15 = - y + 25 \$ |
3 |
Move Variable terms to the left side and constant terms to the right side |
\$ (3y)/4 + y = 25 + 15 \$ |
4 |
Taking LCM as '\$4\$' |
\$ (3y + y)/4 = 40 \$ |
5 |
After simplification |
\$ \cancel(4)^1/\cancel(4)^1 y = 40 \$ |
6 |
After cancelation |
\$ y = 40 \$ |
7 |
Answer |
A = \$ y = 40 \$ |
