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 = 7a - 7x + 6 for a in terms of x.
| \(\frac{9}{14}\)x - \(\frac{3}{7}\) | |
| \(\frac{1}{5}\)x + 1\(\frac{3}{5}\) | |
| 2x + 4 | |
| -\(\frac{14}{15}\)x + \(\frac{7}{15}\) |
