Question

What are the values of x and y in the linear system 5x+8y=36 2x+14y=36

Answer 1

Answer:

7

Step-by-step explanation:

Answer 2

Answer: 3x+5y=9 , 5x+3y=7

Step-by-step explanation:

by doing substituion methob

3x=9-5y

x=(9-5y)/3

putting the value in equation 2 then we get

5 (9 - 5y)/ 3 + 3y=7

45 - 25 y + 3y equals 21

45 - 21 equals 25 y - 9 y

24 equals 16 y

y equals 24 / 16

putting value of y in equation 1 then we get

3  x + 5 * 24 / 16 equals 9

3x equals 9 -  15 / 2

3x plus (18 -15) 2

x equals  1 / 2

so our answer is

ax equals  1 / 2 + 3 / 3

taking I.c.m  bothside

LCM equals 2

then 4/2
