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 -2a - 4a = -7a + 8y - 5 for a in terms of y.
| 3y - 5 | |
| 13y - 3 | |
| 2\(\frac{2}{5}\)y - 1 | |
| -14y + 5 |
