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 = -a + 8x - 9 for a in terms of x.
| 1\(\frac{3}{4}\)x - 1\(\frac{1}{8}\) | |
| x + 1\(\frac{1}{5}\) | |
| -3x + 4 | |
| -\(\frac{1}{2}\)x - \(\frac{7}{12}\) |
