When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 3a - 4a = 5a - 7y + 3 for a in terms of y.
| -\(\frac{2}{3}\)y + 1 | |
| y - 2\(\frac{1}{3}\) | |
| -1\(\frac{1}{4}\)y + \(\frac{3}{4}\) | |
| 1\(\frac{1}{2}\)y - 1\(\frac{1}{2}\) |
