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 - 3a = a + 5x + 4 for a in terms of x.
| -2\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) | |
| x + 6 | |
| x - \(\frac{9}{10}\) | |
| -x + \(\frac{1}{13}\) |
