x= -6
Step-by-step explanation:
5.(x+3) = 2x-3

5x-2x=-3-15
3x=-3-15
3x=-18
x=-6
I believe about 750 this is because of you multiply 150 and 5 you get your answer 750 because each 2 minutes she types is 150 and although you can find your average I just add the average 5 times this would be an easier way!!!
