Question

x+y/2=1 x/3+17y/6=3 solve the pair of linear equation by the substitution method​

Answer 1

Answer:

x = 1/2 = 0.5, y = 1

Step-by-step explanation:

x + y/2 = 1, x = 1 - y/2,

(1 - y/2)/3 + 17y/6 = 3 .....(1)

eqn.1 × 6

2(1 - y/2) + 17y = 18

2 - y + 17y = 18

16y = 18 - 2

y = 1

x = 1 - (1/2) = 1/2
