Question

Mary bought some pants and shirts. when her friends asked her how many of each she had bought, she answered , "the number of shirts is two less than twice the number of pants purchased. also, the number of shirts is four less than four times the number of pants purchased. find the no. of shirts and pants purchased.

Answer 1

let the number of shirts be x

let the number of pants be y

from the given condition,

x=2y-2

x=4y-4

equating two values of x,

2y-2=4y-4

4-2=4y-2y

2 =2y

2/2=y

y=1

sub y=1 in x=2y-2

×=2 (1)-2

×=0
