can you check if how i solved it to show that my answer is no is correct.

Is -4 a solution to the equation 7x-5+3x=6+x-10

This is what i did:

7(-4)-5+3(-4)=6+(-4)-10
-28-5-12=2-10
-45=-8

so the answer is no -4 is not the solution to the equation.

Yes this is fine

yes this is fine

To determine if -4 is a solution to the equation, you correctly substituted -4 for x in the equation and simplified both sides. You obtained -45 = -8, which is false. Therefore, your answer is correct, and -4 is not a solution to the equation. Great work!
