4x+(3x-8)=90
4x+3x-8=90
7x=98
x=98/7
x=14
If x=14,
angle CDJ is:
(3(14)-8) degrees
=34 degrees

You have to do what is called borrowing [type of regrouping ONLY used in Subtraction]. As you can see, 4 minus 9 is impossible to do, so you go one piece value to the left and borrow 1 hundred from 7 hundreds. That becomes 6 and 4 becomes 10 more than 4, which is 14. So now you do your normal subtraction:
14 - 9 = 5
6 - 3 = 3
The rest is normal Subtraction. No more borrowing!
