Answer:
x=1 and y=4/5
Step-by-step explanation:
Given system of equations
3x+5y=7
5x+10y=13
Multiply first equation by 2
2(3x+5y)=2(7)
6x+10y=14
Eliminate y-variable to get "x"
6x+10y=14
- 5x+10y=13
x = 1
Substitute x=1 into either equation and find "y"
3x+5y=7
3(1)+5y=7
3+5y=7
5y=4
y=4/5
Therefore, x=1 and y=4/5
