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 -6a - 6a = -8a - 4x + 4 for a in terms of x.
| x + 2 | |
| 7x + 4 | |
| -\(\frac{11}{13}\)x + \(\frac{9}{13}\) | |
| \(\frac{13}{14}\)x - \(\frac{9}{14}\) |
