2x+2y=16
2x+6y=28we multiply one side negative sing 2x+2y=16
-2x-6y=-28
now add both equation 'x' will be gone
-4y=-12
each side divide by { -4 }
y=3now we get 'Y' then we looking for 'X'
take 3 then blog in one of the orginal equation
2x+2(3)=16
now solve 'X'
2x+6=16
number 6 move to the left side
2x=10
divide each side by 2
x=5
your answer is { Y=3 , X=5 } I THINK YOU UNDERSTAND WHAT I DID. GOOD LUCK
