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 5a - a = 8a - 6y + 6 for a in terms of y.
| -\(\frac{1}{2}\)y - \(\frac{1}{2}\) | |
| 1\(\frac{2}{3}\)y - 2 | |
| y + 1\(\frac{2}{3}\) | |
| -3\(\frac{1}{4}\)y + 1\(\frac{1}{2}\) |
