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 -4b + b = -7b + z - 1 for b in terms of z.
| 11z + 3 | |
| -z + 1\(\frac{1}{2}\) | |
| z - \(\frac{1}{3}\) | |
| \(\frac{3}{4}\)z - 1\(\frac{3}{4}\) |
