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 - 4a = 4a - 4x - 6 for a in terms of x.
| -11x - 2 | |
| \(\frac{1}{12}\)x - \(\frac{1}{4}\) | |
| x + 2 | |
| x + \(\frac{6}{7}\) |
