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 + 3a = 6a + 8x - 2 for a in terms of x.
| -5x + 2 | |
| -\(\frac{4}{7}\)x - 1 | |
| -1\(\frac{3}{8}\)x + \(\frac{3}{8}\) | |
| -\(\frac{5}{11}\)x - \(\frac{6}{11}\) |
