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