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 -5a - 6a = -4a + 4x + 3 for a in terms of x.
| -10x + 7 | |
| 2\(\frac{1}{6}\)x + 1\(\frac{1}{2}\) | |
| -10x - 3 | |
| -2x + \(\frac{3}{8}\) |
