Question

solve 3x+2y=11/3 -7x+5y=31/3

​

Answer 1

Answer:

x=-7/87. , y=170/87

Step-by-step explanation:

let 3x+2y=11/3, -7x+5y=31/3 be eqn. 1 and eqn2 respectively

To get a common term we can multiply eqn1 with 5 and eqn2 with 2.

15x+10y = 55/3----eqn3

-14x+10y = 62/3----eqn4

Subtract eqn3 from eqn4

29x = -7/3

x = -7/87

Substituting value of x in eqn1

3*-7/87+2y=11/3

2y=11/3+7/29

y=170/87
