Question

If 4x + 3y = 10 and x+3y = 7, find the value of x and y?​

Answer 1

Answer:

4(7-3y) +3y =10

28-12y +3y =10

28-9y = 10

18 = 9y

y= 2

x = 7-3(2) = 1

Answer 2

Answer:

4x+3y=10. equation 1

x+3y=7. equation 2

therefore

equation 1 - equation 2

4x+3y=10

-x -3y= -7

3x. =3

x=3/3

x=1

therefore

x+3y=7

(1)+3y=7. [substituting the value of x]

3y=6

y=2

Hope it helps
