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 + a = -2a + 9x + 1 for a in terms of x.
| -\(\frac{11}{15}\)x - \(\frac{4}{15}\) | |
| \(\frac{1}{7}\)x - \(\frac{3}{14}\) | |
| -4x - \(\frac{1}{2}\) | |
| -2\(\frac{3}{4}\)x + \(\frac{3}{4}\) |
