Question

x+2y=1.6 , 2x+y=1.4 solve the problem using substitution method​

Answer 1

Answer:

Step-by-step explanation: x + 2y = 1.6

=> x = 1.6 - 2y

2x + y = 1.4

=> 2x = 1.4 - y

=> x = 0.7 - y/2

Substituting the value of x from Eq. 1 we get :

1.6 - 2y = 0.7 - y/2

=> 1.6 - 0.7 = -y/2 + 2y

=> 0.9 = 3y/2

=> y = 0.6

=> x = 1.6 - 2(0.6)

=> x = 1.6 - 1.2

=> x = 0.4
