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 -4a + 4a = 7a + 5y - 3 for a in terms of y.
| 2\(\frac{1}{2}\)y + 2 | |
| -9y - 8 | |
| \(\frac{2}{5}\)y - 1\(\frac{2}{5}\) | |
| -\(\frac{1}{11}\)y + \(\frac{3}{11}\) |
