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 a - 4a = -6a - 7x + 8 for a in terms of x.
| \(\frac{1}{5}\)x + \(\frac{3}{5}\) | |
| -\(\frac{1}{5}\)x - 1 | |
| x - \(\frac{1}{16}\) | |
| -\(\frac{3}{7}\)x + 1\(\frac{1}{7}\) |
