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