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