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