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