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 -7a + 6a = -6a - 2y + 1 for a in terms of y.
| 3\(\frac{1}{2}\)y + 1 | |
| y + \(\frac{3}{5}\) | |
| y - \(\frac{1}{9}\) | |
| 8y - 1 |
