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 8b - 7b = -7b - 2z + 3 for b in terms of z.
| \(\frac{10}{11}\)z + \(\frac{6}{11}\) | |
| -3\(\frac{1}{2}\)z - 1 | |
| \(\frac{1}{3}\)z + \(\frac{1}{5}\) | |
| \(\frac{2}{3}\)z - 2\(\frac{1}{3}\) |
