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 + 7b = -6b + 2z + 7 for b in terms of z.
| \(\frac{1}{10}\)z + \(\frac{1}{10}\) | |
| -5z + 2 | |
| -1\(\frac{2}{3}\)z + 2\(\frac{1}{3}\) | |
| -3z + 2\(\frac{2}{3}\) |
