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 + 7a = 7a - 9x - 3 for a in terms of x.
| \(\frac{4}{11}\)x - \(\frac{9}{11}\) | |
| 1\(\frac{5}{8}\)x + \(\frac{1}{2}\) | |
| 2\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| 1\(\frac{7}{9}\)x + \(\frac{1}{3}\) |
