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 9c + 6c = -6c - 5z + 4 for c in terms of z.
| \(\frac{1}{18}\)z + \(\frac{4}{9}\) | |
| -\(\frac{11}{15}\)z + \(\frac{4}{15}\) | |
| \(\frac{2}{3}\)z + \(\frac{7}{9}\) | |
| -\(\frac{5}{9}\)z - \(\frac{1}{9}\) |
