Answer:
On cross multiplication we get two equations. These are:
x +2y = 1.6
2x + y = 0.7 .......................... (1)
By elimination method
On multiplying first equation with 2 on both sides we get
2x + 4y = 3.2 ............................. (2)
On subtracting (1) from (2) we get
3y = 2.5
y = 2.5 /3
On putting this value of y in (1)
2x + 2.5 /3 = 3.2
2x = 3.2 - 2.5 /3
2x = 9.6/3 - 2. 5 /3
2x = 7.1/3
x = 7.1/6
