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