Question

−4y+11x−67=0
2y+5x−19=0
solve for x and y

Answer 1

Answer:

x=–5/y=22

Step-by-step explanation:

first we have to multiply–2 from eqn1

and–4 to eqn2

then plus the both eqn and the answer is in picture.

Answer 2

answer:

by elimination method,

11x-4y=67..........eq.1

5x-2y=19...........eq.2

multiply eq.2 by 2

we obtain,

10x-4y=38.........eq.3

substract eq 3 from eq 1

11x+4y=67

- 10x-4y=38

we get x = 29

now substitute value of x in eq.2

19 = 5×29-2y

= 145 -2y

19-145 = -2y

-126 =2y

-126÷2 =y

therefore , y = 63

x=29 and y=63
