Answer:
x=5
Step-by-step explanation:
4x+5=3x+10
All x values must go on the right so subtract 3x from both sides
4x+5=3x+10
-3x -3x
which gets you
x+5=10
Now subtract 5 from both sides to get the value of x
x+5=10
-5 -5
And you get
x=5

The sum is the total of the given values being added.
Given the expressions above, to add them, you just have to add the numbers with the same terms. 13x2 and 8x2 have the same terms which is x2, therefore, you can add both and the result is 21x^2 then just copy 5x so the sum would be 21x2 + 5x. Hope this answer helps.
