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 + 5c = 3c - 6z + 5 for c in terms of z.
| z + 1 | |
| -1\(\frac{2}{7}\)z + \(\frac{3}{7}\) | |
| 11z - 5 | |
| -\(\frac{5}{11}\)z - \(\frac{2}{11}\) |
