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