If x + 3y = 7 and y = 2, then x equals​

X=1

Explanation:

First, let's start by pushing x to the side. As of now, that variable doesn't matter, so that leaves us with 3y = 7.

It informs us already that y = 2, so we're going to multiply 2 x 3 , which gets us 6.

We're now going to flip the equation so we can subtract our total by 6.  7 - 6 gets us 1.

Bringing our x back and using process of elimination, we now know that x = 1.

Full Total Equation:

     1 + 3(2) = 7

           or

     1 + 6 = 7
