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