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 + 9a = 4a - 8y - 2 for a in terms of y.
| y + \(\frac{7}{13}\) | |
| -3y - \(\frac{1}{4}\) | |
| 7y - 3 | |
| 2\(\frac{5}{6}\)y + \(\frac{1}{3}\) |
