Answer» > Frist number =7 and second number is 5
let US assume that Frist number br x and second number as y according to given DATA "four times of a number and 3 times of another number will sum up 43 means" 4x+3y=43 ............ EQUATION 1 and from second condition we get as 2 times of second number was subtract from 3 times of Frist number so it gives 3x-2y=11 ........ equation 2 now solve equation 1 and 2 by any favourable number I am going to do elimination method so the equations made are 4x+3y=43 3x-2y=11 multiple 3 with equation 1 and subtract 4(times of equation 2) that gives 12x+9y=129 12x -8y =44 -. +. = - that gives 17y=85 y=5 now put value of y in equation 2 so 3x-2(5)=11 3x=11+10 3x=21 x=7 therefore the values are 7 and 5 |
