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 -5b + 6b = -8b + 7z - 2 for b in terms of z.
| z + 3 | |
| \(\frac{7}{9}\)z - \(\frac{2}{3}\) | |
| \(\frac{1}{3}\)z - \(\frac{1}{3}\) | |
| \(\frac{1}{3}\)z - \(\frac{2}{3}\) |
