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 -7a - 3a = -a - 2x + 7 for a in terms of x.
| \(\frac{2}{7}\)x + 1\(\frac{2}{7}\) | |
| x - \(\frac{1}{3}\) | |
| \(\frac{4}{11}\)x - \(\frac{6}{11}\) | |
| -\(\frac{1}{6}\)x - 1\(\frac{1}{6}\) |
