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