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 -3a + 2a = 6a - 4x + 7 for a in terms of x.
| \(\frac{3}{7}\)x - \(\frac{5}{14}\) | |
| \(\frac{14}{17}\)x + \(\frac{3}{17}\) | |
| -\(\frac{2}{5}\)x + 1\(\frac{1}{5}\) | |
| \(\frac{2}{3}\)x - \(\frac{7}{9}\) |
