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 -3c - 8c = -4c + 6z + 7 for c in terms of z.
| \(\frac{4}{15}\)z - \(\frac{8}{15}\) | |
| -2\(\frac{1}{3}\)z - 2\(\frac{2}{3}\) | |
| 14z + 7 | |
| z + 1\(\frac{3}{5}\) |
