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 -8c + 2c = 6c - 5z - 6 for c in terms of z.
| -15z + 2 | |
| \(\frac{1}{2}\)z + \(\frac{3}{7}\) | |
| z - \(\frac{3}{4}\) | |
| \(\frac{3}{8}\)z + \(\frac{1}{2}\) |
