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 -8a + 2a = -9a + 2y + 2 for a in terms of y.
| 8y - 5 | |
| \(\frac{1}{15}\)y + \(\frac{2}{15}\) | |
| y + 2 | |
| -3\(\frac{3}{4}\)y + \(\frac{1}{4}\) |
