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 - 5a = -9a - 5x - 4 for a in terms of x.
| 2\(\frac{1}{3}\)x + 1 | |
| x - \(\frac{2}{3}\) | |
| x - \(\frac{1}{7}\) | |
| x - \(\frac{4}{5}\) |
