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