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