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 -2a + 2a = 8a + 9x + 5 for a in terms of x.
| \(\frac{9}{10}\)x + \(\frac{9}{10}\) | |
| -x + 1\(\frac{2}{3}\) | |
| -2x - \(\frac{2}{3}\) | |
| -\(\frac{7}{10}\)x - \(\frac{1}{2}\) |
