Question

solve
3y+4x=10 and x+4y=9​

Answer 1

Answer:

x is 1

y is 2

Step-by-step explanation:

3y + 4x = 10 --(1)

x + 4y = 9

x = 9 - 4y --(2)

Put value of x in eq.--(1)

3y + 4(9 - 4y) = 10

3y + 36 - 16y = 10

3y - 16y = 10 - 36

-13y = -26

13y = 26

y = 26/13

y = 2

put value of y in eq.--(1)

x = 9 - 4(2)

 = 9 - 8

 = 1
