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 -a + 2a = -4a + 2x - 7 for a in terms of x.
| 1\(\frac{2}{11}\)x - \(\frac{9}{11}\) | |
| 2\(\frac{1}{2}\)x - 1 | |
| 2\(\frac{3}{4}\)x + 2\(\frac{1}{4}\) | |
| x - 2\(\frac{1}{3}\) |
