Question

solve by elimination method x by 3+ y by 3=14 and 5x by 6-y by 3 +7=0​

Answer 1

Answer:

Step-by-step explanation:

x/3+y/4=11

multiplying by 12, then

4x+3y =132.......(1)

5x/6-y/3+7 =0

5x/6-y/3= -7

multiplying by 18, then

15x-6y= -126........(2)

in equation (1) multiplying by 2, then, 8x+6y =264........(3)

(2)+(3)

we get, 23x =138

ie, x= 138/23= 6

ie, x=6

put the value of x into equation (1), we get,

24+3y=132

3y =108

y =36

we get the values are x=6 and

y = 36
