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 -7c + 4c = -8c + 4z + 6 for c in terms of z.
| \(\frac{5}{12}\)z + \(\frac{1}{6}\) | |
| -\(\frac{1}{7}\)z + \(\frac{2}{7}\) | |
| z + 6 | |
| z + 2\(\frac{1}{4}\) |
