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