Step-by-step explanation:
<u>Step 1: Define</u>
3x - 4y = 7
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 4y to both sides: 3x = 4y + 7
- Divide 3 on both sides: x = (4y + 7)/3
Answer:
4y + 3
Step-by-step explanation:
All we can do here is to simplify the given expression; this is not an equation and thus has no solution.
5y - y is 4y, so
5y - y + 3 = 4y + 3
