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 6b + 2b = -2b + 2z + 4 for b in terms of z.
| -3z + 3 | |
| -\(\frac{8}{13}\)z + \(\frac{8}{13}\) | |
| -1\(\frac{4}{9}\)z - 1 | |
| z + \(\frac{1}{2}\) |
