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 -8a + 7a = 6a + 5x + 3 for a in terms of x.
| -\(\frac{9}{13}\)x - \(\frac{6}{13}\) | |
| -\(\frac{1}{4}\)x - \(\frac{7}{12}\) | |
| \(\frac{1}{7}\)x - \(\frac{3}{14}\) | |
| -\(\frac{5}{9}\)x + \(\frac{5}{9}\) |
