Solve by elimination or 3/4 x - 1/3 y = -1/2 -1/2 x + 2/5 y = -1/5 Solve by graphing - use straight

3x/4 - y/3 = -1/2 ----(1)

-x/2 + 2y/5 = -1/5 ---(2)

------Mulitply equ 2 by 3/2

3x/4 + y/3 = -1/2

-3x/4 + 3y/5 = -3/10

----------------------------- add

y( 1/3 + 3/5) = (-5 -3)/10

14y/15 = -8/10

y = -8*15/10*14 = -4*3/5*7

= -12/35

y = -12/35

Substitute to get x: -x/2 - 24/175 = -1/5

-x/2 = -1/5 + 24/175 = ( -35 +24)/175 = -11/175

x= 22/175
