<span>A) 3x+4y=17
B) -4x-3y=-18 Multiplying B) by .75
</span><span>B) -3x -2.25y= -13.5 then adding this to A
</span><span><span>A) 3x + 4y = 17</span>
1.75y = 3.5
y = 2
</span><span>
A) 3x + 4*2 = 17</span>
3x + 8 = 17
3x = 9
x = 3
(3,2)
Ok so x has to be our unknown variable so 3/4x=20 so we divide keep change flip or kfc as we call it 3/4 times 1/20 would be 3/80
