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 -6b + 4b = -7b - 6z + 8 for b in terms of z.
| -\(\frac{2}{9}\)z - \(\frac{1}{9}\) | |
| -5z - 3 | |
| -10z + 8 | |
| -1\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) |
