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 7b + 2b = -4b - 9x - 4 for b in terms of x.
-x - \(\frac{4}{11}\) | |
-\(\frac{2}{3}\)x + \(\frac{7}{9}\) | |
-3x - 3 | |
-1\(\frac{3}{7}\)x + \(\frac{3}{7}\) |
