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 = 7b + 5y - 7 for b in terms of y.
| -\(\frac{3}{10}\)y + \(\frac{7}{10}\) | |
| -\(\frac{2}{3}\)y + 1 | |
| -\(\frac{1}{13}\)y + \(\frac{3}{13}\) | |
| \(\frac{1}{4}\)y - \(\frac{1}{4}\) |
