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