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 -4b + 2b = 3b + 8z - 7 for b in terms of z.
| \(\frac{1}{4}\)z + \(\frac{5}{12}\) | |
| \(\frac{1}{10}\)z + \(\frac{1}{2}\) | |
| -\(\frac{6}{7}\)z + 1 | |
| 14z + 3 |
