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