Question 496759
this equations system is representing the problem
x-y=7
x/2+2y=51
.
x-y=7 *(2) multiplying to when you sum delet y
x/2+2y=51
.
2x-2y=14
x/2+2y=51 suming
___________
2x+x/2+0y=65
2x+x/2=65
4x/2+x/2=130/2 make the denominators equal to delete them
4x+x=130
5x=130
x=130/5
x=26
now substituting x to find y
x-y=7
26-y=7
26-7=y
19=y
the numbers are 19 and 26
