5x + 2y=50
or
5x + 2y<=50 (less than or equal to)
then
x + 2y=30
or
x + 2y<=30(less than or equal to)
In order to solve this equation you must eliminate one of the variables.
By multiplying by -3 you eliminate the y variable, making A the correct answer.
-6x-3y=-66
5x+3y=29
-x=-37
x=37
If you would like further explanation let me know. :)
The answer is N=13(x+12), where x represents the amount of pounds Steven's boxes weighed and N represents the total number of pounds Nathan lifted.
