Verified Answer :

2x+3y=7
x-y=1

2x+3y=7
x=1+y

2(1+y)+3y=7
x=1+y

2+2y+3y=7
x=1+y

5y=5       |(:5)
x=1+y

y=1
x=2

CHECK:
2x+3y=7
x-y=1

22 + 3*1 = 7     

x-y = 1
2-1 = 1

2x+3y=7                                               
2(2)+3y=7                                                                                              
4+3y=7
subtract 4 from both sides                  
3y=3                                             
divide both side by 3                          
y=1
 

2x+3y=7


2x+3=7


2x+3y=7

subtract 3y from both
sides


2x=7-3y


divide both side by 2

x=3.5-1.5


x=2



then you do the x-y=1

x-y=1
2-1=1
1=1

in the end both answers are 1 so that means that i did it right. that means that x=2 and y=1
