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 9a - 4a = -2a + x + 6 for a in terms of x.
| \(\frac{6}{7}\)x + \(\frac{4}{7}\) | |
| -1\(\frac{1}{9}\)x + 1 | |
| -5\(\frac{2}{3}\)x + 1 | |
| \(\frac{5}{11}\)x + \(\frac{6}{11}\) |
