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 = -2c - 5z + 7 for c in terms of z.
| \(\frac{1}{3}\)z + \(\frac{2}{3}\) | |
| z - \(\frac{5}{7}\) | |
| -4z + 2 | |
| \(\frac{3}{10}\)z + \(\frac{7}{10}\) |
