13+5x-2x=37 what does x equal show work thanks
13 + 5x - 2x = 37
First combine the like terms on the left which are
+5x and -2x. That gives you +3x. So you replace
"+ 5x - 2x" by "+ 3x". So now you have this:
13 + 3x = 37
Since you want to get the x-term, +3x, all by itself
we get rid of the 13 term on the left by adding its
opposite, -13, to both sides
13 + 3x = 37
-13 -13
------------------
3x = 24
When we get to this stage, where there is just one
term on the left consisting of a coefficient and the
unknown, then you divide both sides by that
coefficient, which is 3.
3x 24
---- = ----
3 3
Then the 3's cancel on the left and the 3 goes into the
24 8 times on the right:
1 8
3x 24
---- = ----
3 3
1 1
so the answer is:
x = 8
