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