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 -9a + 4a = -6a - 2y - 6 for a in terms of y.
| \(\frac{3}{8}\)y - \(\frac{7}{16}\) | |
| 2y + 2 | |
| 2y + 1\(\frac{1}{6}\) | |
| -3\(\frac{1}{2}\)y + 4 |
