Answer:
13=x
Step-by-step explanation:
Side-spliting theorem
21/(x-4)=14/6
cross multiply
21*6=14*(x-4)
distribute 14
126=14x-56
add 56 to both sides
126+56=14x-56+56
leaving you with
182=14x
Divide both sides by 14 to get x by itself
182/14=14x/14
13=x
4x + 2
Eg 4 times 2 =8 +2 =10
-10.4
subtract 5.2 on each side because it’s the inverse operation
hope this helps!
