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 + 3a = -5a + 2x - 6 for a in terms of x.
| 1\(\frac{1}{6}\)x - 1\(\frac{1}{3}\) | |
| -9x + 7 | |
| -\(\frac{1}{12}\)x - \(\frac{1}{2}\) | |
| -1\(\frac{1}{6}\)x + \(\frac{5}{12}\) |
