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 -4c + 7c = 3c - 5z - 3 for c in terms of z.
| \(\frac{9}{10}\)z + \(\frac{1}{10}\) | |
| -z - 5 | |
| \(\frac{4}{9}\)z - \(\frac{5}{9}\) | |
| 1\(\frac{5}{7}\)z + \(\frac{3}{7}\) |
