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