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