solve x+3y=16 2x+3y=4 solution
Answers
Answer:
x+3y=16
so,x=16-3y
put this value in other equation
2(16-3y)+3y=4
32-3y=4
3y=28
y=28/3
Answer:
Step-by-step explanation:
Given:
x + 3y = 16 ………………. (1)
2x + 3y = 04 ………………. (2)
Now we subtract equation (1) from equation (2) , We get
(x + 3y) – (2x + 3y) = 16 – 4
x + 3y – 2x - 3y = 12
-x = 12
x = - 12 …………….. (3)
Now from equation (3) Putting the value of x in equation (1)
-12 + 3y = 16
3y = 16 + 12
3y = 28
y = 28/3 = 9.33
So, we get x = -12 & y = 9.33 Ans.
