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 - 8c = 6c - 4z + 2 for c in terms of z.
| -5z - 5 | |
| 4z + 2 | |
| \(\frac{3}{5}\)z - \(\frac{3}{5}\) | |
| 1\(\frac{1}{4}\)z - 1\(\frac{3}{4}\) |
