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 -7a + 6a = 3a + 3x - 8 for a in terms of x.
| 1\(\frac{4}{11}\)x - \(\frac{9}{11}\) | |
| \(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -\(\frac{9}{13}\)x - \(\frac{5}{13}\) | |
| \(\frac{3}{10}\)x + \(\frac{4}{5}\) |
