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 + 3b = -5b - 2z + 2 for b in terms of z.
| 11z - 4 | |
| \(\frac{9}{10}\)z + \(\frac{4}{5}\) | |
| 2\(\frac{1}{2}\)z - 1 | |
| \(\frac{2}{3}\)z + \(\frac{1}{3}\) |
