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 -9a + 9a = -6a + 3x + 2 for a in terms of x.
| 8x + 3 | |
| -1\(\frac{1}{7}\)x - \(\frac{1}{14}\) | |
| 2x - \(\frac{2}{3}\) | |
| 1\(\frac{2}{11}\)x + \(\frac{7}{11}\) |
