0.4 (x-3) = 0.05 (y+2) 0.2 (x+y) = 0.1 (6y+8) Solve the pair of equation by cross multiplication method Share with your friends Share 1 Ashwini Kumar answered this We have,0.4x-3=0.05y+2⇒8x-3=y+2 Multiplying both sides by 20⇒8x-24=y+2⇒8x-y=26 .....1And0.2x+y=0.16y+8⇒2x+y=6y+8 Multiplying both sides by 10⇒2x+2y=6y+8⇒2x-4y=8 .....2From 1-2×4, we get 8x- y=26 8x-16y=32 0 +15y=-6⇒y=-615=-25=-0.4putting y=-0.4 in 1, we get8x+0.4=26⇒8x=25.6⇒x=25.68=3.2Hence, x=3.2 and y=-0.4 6 View Full Answer
