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 - 4a = -7a - 5x + 3 for a in terms of x.
| -5\(\frac{2}{3}\)x + 3 | |
| -\(\frac{2}{13}\)x - \(\frac{8}{13}\) | |
| \(\frac{1}{2}\)x - 1 | |
| -\(\frac{1}{8}\)x + \(\frac{3}{8}\) |
