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 -5a - 5a = 8a - 9x + 7 for a in terms of x.
| \(\frac{4}{13}\)x - \(\frac{7}{13}\) | |
| 12x - 8 | |
| \(\frac{1}{3}\)x + \(\frac{5}{6}\) | |
| -1\(\frac{1}{12}\)x + \(\frac{1}{6}\) |
