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 8c - 8c = 6c - 9x + 8 for c in terms of x.
x - 8 | |
-\(\frac{3}{14}\)x + \(\frac{1}{7}\) | |
-\(\frac{1}{2}\)x + 4 | |
-\(\frac{6}{13}\)x - \(\frac{3}{13}\) |
