0.4x + 0.3y =1.70.7x -0.2y =0.8Solve the following system of equation

1.	0.4x + 0.3y =1.70.7x -0.2y =0.8Solve the following system of equation
Answer» O.4x+0.3y=1.7 4/10x+ 3/10y=17/104x+3y/10=17/104x+3y=17 -----(1)Similarly 7x-2y=8-----(2)4x=17-3y X=17-3y/4---(3)Puting (3) in (2)7 (17-3y/4)-2y =8119-21y/4 -2y=8Taking lcm119-21y-8y=8×4-29y=36-119-29y=-83Y=3 7x-2 (3)=87x=8+6X=14/2X=2,y=3
