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 = 4c - 8z - 6 for c in terms of z.
| -4z - 3\(\frac{1}{2}\) | |
| \(\frac{8}{11}\)z + \(\frac{3}{11}\) | |
| z + 7 | |
| -\(\frac{1}{4}\)z - 1\(\frac{1}{2}\) |
