The numbers are #22# and #23#

Explanation:

Alright, to solve a problem like this, we need to read and define as we go. Let me explain.

So we know that there are two consecutive integers. They can be #x# and #x+1#. Since their consecutive, one has to be #1# number higher (or lower) than the other.

Ok, so first we need "seven times the larger"

#7(x+1)#

Next, we need to "minus three times the smaller"

#7(x+1)-3x#

Is equal to "#95#"

#7(x+1)-3x=95#

Alright! There's the equation, now we just need to solve for #x#! First we are going to get everything on one side and distribute the #7#.

#=7x+7-3x-95#

#=4x-88#

Pull out a #4#

#=4(x-22)#

Now that we have two terms, we can set them both equal to #0# and solve.

#4!=0#

This can never be true, lets move to the next term

#(x-22)=0#

#x=22#

That's it! So your two consecutive numbers are #22# and #23#!

If you want to check this, just put #22# in place of the #x# and #23# in place of the #(x+1)# in the equation we made above!

Hope this helps!
