19x+5+16x=180<br> I need help with this I don’t understand
EleoNora [17]

Hello!

--------------------------------------------------------------------------------------------------------------

19x+5+16x=180

First, add the x's together:

35x+5=180

Now, subtract 5 from both sides:

35x=180-5

35x=175

Divide both sides by 35 to isolate x:

x=5

Hope you find my answer helpful! Please give the crown if you do! (:
