??????????????? "solv expresshun" ?????????????
if yu "solv" sumthun, it gotta be equashun & yu giv us 2 equashuns
line 1: 3x -5y=10 or 5y=3x-10 wich become y=(3/5)x -2
line 2: 2x+7y=15
line2...2x +7[(3/5)x -2]=15
2x +(21/5)x -14=15
(27/5)x=29
27x=145
x=145/27=5.37037073737373737 or 5 & 10/27
y=(3/5)x-2 or(87/27)-2=(87-54)/27=33/27=1.22222222222222222
