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 + 5z + 8 for c in terms of z.
| 3\(\frac{3}{4}\)z + 1\(\frac{1}{4}\) | |
| 12z + 8 | |
| 11z - 9 | |
| 2z - 7 |
