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