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 - 7b = -7b + 9x - 9 for b in terms of x.
1\(\frac{3}{13}\)x - \(\frac{9}{13}\) | |
-1\(\frac{3}{4}\)x - \(\frac{1}{4}\) | |
10x - 4 | |
-\(\frac{1}{2}\)x + 1 |
