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 -3a + 8a = 7a - 7x + 5 for a in terms of x.
| 1\(\frac{1}{2}\)x - \(\frac{1}{2}\) | |
| 3\(\frac{1}{3}\)x - 1\(\frac{1}{3}\) | |
| 3\(\frac{2}{3}\)x - \(\frac{2}{3}\) | |
| -\(\frac{1}{10}\)x + \(\frac{4}{5}\) |
