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 + 2a = 3a + 8y - 7 for a in terms of y.
| \(\frac{1}{4}\)y + \(\frac{5}{12}\) | |
| \(\frac{1}{10}\)y + \(\frac{1}{2}\) | |
| -\(\frac{6}{7}\)y + 1 | |
| 14y + 3 |
