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 + 3a = -6a - 7x - 4 for a in terms of x.
| 2x + 5 | |
| -10x - 4 | |
| -\(\frac{1}{3}\)x - 1\(\frac{1}{2}\) | |
| -13x - 6 |
