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 - 4a = 3a + 5x + 1 for a in terms of x.
| -\(\frac{9}{10}\)x - \(\frac{1}{10}\) | |
| 10x + 4 | |
| \(\frac{1}{5}\)x + \(\frac{4}{5}\) | |
| -\(\frac{3}{4}\)x - \(\frac{3}{4}\) |
