Combine like terms

-x = 4 + 6 - 3x
-x = 10 - 3x

Isolate the x, add 3x to both sides

-x (+3x) = 10 - 3x (+3x)

-x + 3x = 10

Simplify. Combine like terms

-x + 3x = 10

2x = 10

Isolate the x, divide 2 from both sides

2x/2 = 10/2

x = 10/2

x = 5

x = 5, or A is your answer

hope this helps
The answer is 5 because first you would add 3x to both sides and then you would have 2x on the left so your equation now would be 2x=4+6 which we can simplify to 2x=10 then you divide both sides by two and you get 5. Hope this helps!
