HanAkoSolo (jamierox4ev3r):

first, simplify the y

HanAkoSolo (jamierox4ev3r):

y-2x>4 +2x +2x y>2x+4

HanAkoSolo (jamierox4ev3r):

then plug it in to do substitution

HanAkoSolo (jamierox4ev3r):

3x<2(2x+4)-3 3x<4x+8-3 3x<4x+5 -4x -4x -x<5 x>5

HanAkoSolo (jamierox4ev3r):

x is greater than 5. then you use this to solve for y

HanAkoSolo (jamierox4ev3r):

y-2(5)>4 y-10>4 +10 +10 y>14 3(5)<2y-3 15<2y-3 +3 +3 18<2y y>14

HanAkoSolo (jamierox4ev3r):

y is greater than 14

HanAkoSolo (jamierox4ev3r):
