What is the value of x in the equation 2x + 3y = 36, when y = 6

Hey buddy!

They give you the equation 2x + 3y = 36, when y = 6

So, the first thing that should come into your mind is replace 6 by y. As you can see, we have 3y in the equation, so we said we would replace the y with 6. So, it will 3(6). Got it? Good

So now let's solve it then...

2x + 3y = 36

2x + 3(6) = 36

2x + 18 = 36

Add -18 to both sides

2x + 18 - 18 = 36 - 18

2x = 18

Then divide both sides by 2

2x/2 = 18/2

x = 9

Thus,

The value of x is 9.



If you want to double check your work, to make sure you got it. We gonna go back to the equation then we will replace y by 6 and x by 9. Then we should get 36.

Let's try it out

2x + 3y = 36

2(9) + 3(6) = 36

18 + 18 = 36

36 = 36

So yes, we did right.

The value of x is 9

I hope this helps!

Thanks!

The value of x is 9 since 2 x 9(18) + 3 x 6 (18) 18+18= 36 (x = 9)
