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 -8a + 9a = -7a - 8x + 6 for a in terms of x.
| -2x - \(\frac{4}{5}\) | |
| 17x - 6 | |
| \(\frac{4}{5}\)x + \(\frac{1}{5}\) | |
| \(\frac{8}{9}\)x - \(\frac{1}{3}\) |
