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 + 7c = 3c - 4z - 4 for c in terms of z.
| \(\frac{7}{13}\)z + \(\frac{8}{13}\) | |
| -\(\frac{6}{11}\)z - \(\frac{6}{11}\) | |
| z + \(\frac{4}{11}\) | |
| z - \(\frac{8}{11}\) |
