2x+4y=1 x5
3x-5y=7
will you tell me the answer quick

2x+4y = 1                     
3x- 5y = 7
Multiply both equation by a number to get rid of one variable I used y because it had opposite signs so multiply top equation by 5 and bottom by 4
you get,
10x + 20y = 5
12x  - 20y = 28
solve the equation we get,
22x = 33 
x = 33/22
x = 1.5
substitute this value in other equation to get y 
2x + 4y = 1
2(1.5) + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4
y = -0.5
so answer is x = 1.5 and y = -0.5
( 1.5, -0.5)

The difference is 5,100m?
