so for elimination, i suggest multiplying the first equation by negative 4 to get rid of x, than solve for y. for the substitution part, any one will work just fine, just isolate one variable

7x  3y = 20 5x + 3y = 16 To eliminate you add together the top and bottom equation so you get 12x = 36 x= 3 Then you can work out y 5x3 +3y = 16 15+3y = 16 3y= 1 y= 1/3

watch it though inspy, i think that was a .5x

The first one is wrong. I forgot to multiply the 6 by 6

y=.5x6 and 2x+6y=19 so multiply the first eq by 4 to get: 4y=2x24 = 4y2x=24 now take that and add the two to get: 10y=5 so y =1/2 then just solve for x using the known yvalue for the substitution: remember from your first eq that y=.5x6, so just sub that into the second eq: 2x+6(.5x6)=19 and solve

y = 1\2x  6 2x + 6y = 19 6y = 3x36 6y= 192x 3x36=192x 5x= 55 x= 11 y= 0.5 Thanks Mr Doe
