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 -8a + 2a = 2a + 8x + 2 for a in terms of x.
| -10x + 6 | |
| -\(\frac{2}{7}\)x + \(\frac{1}{7}\) | |
| \(\frac{1}{13}\)x - \(\frac{1}{13}\) | |
| -\(\frac{3}{5}\)x - \(\frac{1}{5}\) |
