Question

solve each system of equations
2x+y=5
3x-2y=4

Answer 1

from 1st equation,
2x+y=5
=>y=5-2x
from 2nd equation,
3x-2y=4
=>3x-4=2y
=>y=(3x-4)/2
comparing y values,
5-2x=(3x-4)/2
=>2(5-2x)=3x-4
=>10-4x=3x-4
=>10+4=3x+4x
=>14=7x
=>14/7=x
=>x=2
putting the value of x,
y=5-2x=5-2(2)=5-4=1
so the answer is x=2, y=1
