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 -4a + 8a = -9a + 9x + 8 for a in terms of x.
| \(\frac{1}{5}\)x + 1\(\frac{3}{5}\) | |
| 6x + 3 | |
| 2x - 1\(\frac{3}{4}\) | |
| -\(\frac{3}{4}\)x + 2\(\frac{1}{4}\) |
