Question

if 4x+9y=13 AND 3x+y=4 what is the value of x

Answer 1

Answer:

4x+9=13

4x=13-9=4

x=4/4=1

3x+y=4

3x1+y=4

y=4-3=1

Step-by-step explanation:

Answer 2

Answer: x = 1 and y = 1

Step-by-step explanation:

Given :-

4x + 9y = 13 and 3x + y = 4,

So if 3x + y = 4,

27x + 9y = 36

Now, subtracting the equation 4x + 9y = 13 from 27x + 9y = 36,

23x = 23,

⇒x = 1, correspondingly, y = 1
