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 3c + c = -7c + z - 9 for c in terms of z.
| \(\frac{10}{13}\)z + \(\frac{8}{13}\) | |
| z - \(\frac{7}{15}\) | |
| 3z + 5 | |
| z - \(\frac{9}{10}\) |
