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 + 2b = b + 8z - 4 for b in terms of z.
| \(\frac{11}{15}\)z + \(\frac{1}{5}\) | |
| -\(\frac{2}{3}\)z + \(\frac{4}{9}\) | |
| -7z - 9 | |
| -\(\frac{1}{7}\)z - \(\frac{1}{7}\) |
