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 -5a + 5a = 2a - 4x + 8 for a in terms of x.
| 1\(\frac{2}{13}\)x + \(\frac{8}{13}\) | |
| 1\(\frac{2}{7}\)x - 1\(\frac{1}{7}\) | |
| 1\(\frac{2}{15}\)x + \(\frac{3}{5}\) | |
| x + 1\(\frac{3}{5}\) |
