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