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 - 2a = -7a - 3x + 4 for a in terms of x.
| -5\(\frac{2}{3}\)x + 3 | |
| \(\frac{1}{16}\)x + \(\frac{1}{8}\) | |
| -\(\frac{1}{3}\)x + 1\(\frac{1}{3}\) | |
| -\(\frac{2}{7}\)x - 1 |
