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 + 6b = -7b - 5z + 8 for b in terms of z.
| -3z - 8 | |
| 16z - 2 | |
| -2\(\frac{1}{5}\)z + 1\(\frac{3}{5}\) | |
| 2z - 4 |
