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 - a = 4a - 7x + 3 for a in terms of x.
| \(\frac{6}{7}\)x - \(\frac{3}{7}\) | |
| -x - 6 | |
| \(\frac{4}{15}\)x - \(\frac{7}{15}\) | |
| -\(\frac{1}{3}\)x - \(\frac{2}{3}\) |
