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 -7a - 3a = -8a - y - 6 for a in terms of y.
| 1\(\frac{1}{5}\)y - 1\(\frac{4}{5}\) | |
| 4y + 9 | |
| 2y - 7 | |
| 2y - 6 |
