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 - 9a = -7a - 8x - 3 for a in terms of x.
| -\(\frac{1}{4}\)x + \(\frac{2}{3}\) | |
| 3x + 2 | |
| \(\frac{1}{11}\)x - \(\frac{3}{11}\) | |
| 2\(\frac{2}{3}\)x + \(\frac{1}{3}\) |
