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 4c + 4c = -5c - 2z + 7 for c in terms of z.
| -\(\frac{2}{3}\)z + \(\frac{7}{9}\) | |
| -z + 1 | |
| \(\frac{3}{5}\)z - \(\frac{4}{15}\) | |
| z + \(\frac{2}{11}\) |
