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 7a + 7a = -6a + 4x + 6 for a in terms of x.
| -\(\frac{3}{5}\)x + \(\frac{3}{5}\) | |
| -\(\frac{3}{13}\)x + \(\frac{6}{13}\) | |
| x + \(\frac{3}{14}\) | |
| 1\(\frac{1}{2}\)x + \(\frac{2}{3}\) |
