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 + 5a = 8a - 8x - 5 for a in terms of x.
| -\(\frac{3}{4}\)x + \(\frac{3}{8}\) | |
| \(\frac{5}{7}\)x + 1\(\frac{2}{7}\) | |
| 1\(\frac{1}{3}\)x + \(\frac{8}{9}\) | |
| 2\(\frac{1}{6}\)x + \(\frac{5}{6}\) |
