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