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 4a + 3a = 7a - 5x - 1 for a in terms of x.
| \(\frac{2}{3}\)x - \(\frac{1}{2}\) | |
| 2\(\frac{2}{3}\)x + \(\frac{1}{3}\) | |
| -\(\frac{4}{11}\)x - \(\frac{8}{11}\) | |
| \(\frac{1}{13}\)x - \(\frac{7}{13}\) |
