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 6c + 4c = 7c + 8z + 2 for c in terms of z.
| -z - 2 | |
| -11z + 1 | |
| -3\(\frac{1}{3}\)z - 2 | |
| -4z - 2 |
