Question

pants/shirt cost $71.90. shirt cost $20 less than pants, what's the cost of the shirt? what's cost of pants/  my answer: shirt $14.38 pants $57.52

anonymous · Answer

that cannot be right because 57.52 is not 20 more than 14.38

anonymous · Answer

put say x = amount of shirt, so 
$$x+20$$ is the price of the pants and then solve 
$$x+x+20=71.90$$

anonymous · Answer

sure
first perhaps write 
$$2x+20=71.90$$ then subtract 20 from both sides.  what do you get?

anonymous · Answer

$ 29.90 shirt and pants $42.00

anonymous · Answer

again that cannot be correct, because the pants are $20 more than the shirt and 42 is not 20 more than 29.90

anonymous · Answer

$$2x+20=71.90$$
$$2x=51.90$$
$$x=51.90\div 2$$
$$x=25.95$$

anonymous · Answer

shirt is $25.95, pants are $45.95
