thanks whats the next step

Answer 12

So now what is 7 · x + 7 · 9 ?

it would be 7x + 63

Answer 13

so the problem looks like this 98 = 7x +63

Answer 14

okay

Answer 15

Now your goal is to get x alone on one side. In order to do this you have to subtract 63 by both sides and then you'll get
35 = 7x

now you divide 7 by both sides and you'll get 35 divide by 7 is?
