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 10c + 7c = 9c + 8z + 6 for c in terms of z.
| -2\(\frac{2}{3}\)z + \(\frac{1}{3}\) | |
| -6z - 1\(\frac{1}{2}\) | |
| 6z - 3 | |
| z + 6 |
