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 -2b + 7b = 2b - 8y - 7 for b in terms of y.
| -\(\frac{3}{11}\)y + \(\frac{9}{11}\) | |
| -\(\frac{7}{15}\)y - \(\frac{8}{15}\) | |
| \(\frac{1}{13}\)y + \(\frac{6}{13}\) | |
| 3\(\frac{3}{4}\)y + 1\(\frac{3}{4}\) |
