Distribute 7*14 = 98 then 7*-x = -7x then put the equation together so
-7x-98=3x+18
The next thing to do is add -98 to both sides
So the equation is
-7x = 3x -80
Then the 3x, subtract on the left side
So the equation is
-10x = -80
Then after you’d have to divide by -10 on both side so the equation is now
x=8
