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