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 -4a - 5a = 8a - x + 2 for a in terms of x.
| -\(\frac{1}{3}\)x - \(\frac{1}{6}\) | |
| -12x + 5 | |
| 2\(\frac{1}{4}\)x - 2 | |
| -\(\frac{1}{2}\)x + 1 |
