Question

What is the value of x in the equation 3x-4y=65, when y=4?

Answer 1

27

Step-by-step explanation:

First, you multiply 4 x 4 because y=4. The product is 16. Then, you add 65 and 16 to get 81, which would equal 3x. Since x is being multiplied by 3 and you know what the product is, you divide 81 by 3 to get 27. Therefore, x=27.

Answer 2

Step-by-step explanation:

4x4=16. So think of it like this now..

3x-16=65

Add 16 in each side and you get 3x=81. Divide 3 with 81 and should be 27, or x=27.

Then you check it by putting in the #'s

3(27)-4(4)=65

81-16=65

65=65 ✔️
