How do you expand the expression 3(x+11)

In brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!

this means that it has to be

3 x X + 3 x 11

this means that we can also multyplay 3 by 11 now. 

and that equals to 33. There fore the expansion will be: 

3 x X + 33

we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)

so the expansion for 3(x+11) is 3x + 33

The correct answer is -20y

The solution to the system of equations (-2,2)
