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 -2a + 6a = -a + 6x + 5 for a in terms of x.
| x - 5 | |
| -2\(\frac{3}{5}\)x - \(\frac{4}{5}\) | |
| -\(\frac{7}{11}\)x + \(\frac{8}{11}\) | |
| -1\(\frac{1}{8}\)x + \(\frac{7}{8}\) |
