2x+7y=48,

x=44-6y

substitute x in the first equation the result is:

2(44-6y)+7y=48

88-12y+7y=48

-5y=48-88=-40

y=-40/-5=8

x=44-6(8)=44-48=-4

The solution set for the system 2x+7y=48, x=44-6y is (-4, 8)

x=44-6y

substitute x in the first equation the result is:

2(44-6y)+7y=48

88-12y+7y=48

-5y=48-88=-40

y=-40/-5=8

x=44-6(8)=44-48=-4

The solution set for the system 2x+7y=48, x=44-6y is (-4, 8)
