Question

45x+7y=10 and 15x+14y=5 solve this linear equation by elimination method​

Answer 1

Step-by-step explanation:

45x+7y=10..........1

15x+14y=5..........2

from eq 1 and 2

45x+7y=10. ×2

15x+14y=5. ×1

90x+14y=20

15x+14y=5

75x=15

X= 75/15

x=5............3

put equation 3 value in 1

45×3+7y=10

135+7y=10

7y= -125

y= -17
