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 = -5a + 5y + 4 for a in terms of y.
| \(\frac{4}{15}\)y + \(\frac{3}{5}\) | |
| 2y + 9 | |
| 3y + 4 | |
| -7y - 2 |
