X=-1
Add 4x to both sides:
3=10x+13
Subtract 13 from both sides
-10=10x
Divide by 10: -1=x

Easy peasy...balance the equation.
Get all the x’s on onside, all the whole’s on the other and then divide to find x.
sorry no answer from me...do the homework.

3 - 4x = 6X + 13
3-4x (+4x) = 6X+13 (+4x)
3 = 10x + 13
3 (-13) = 10x + 13 (-13)
-10 = 10x
-10/10 = x
-1=x

This is a website that we always use. It solves the problem, but also shows how to get the answer.

If I could spell "Algebra" I will tell you in my miniscule brain x never equals a number, I mean WTH! how can a letter equal a number.
Algebra is obviously a tool of the devil! it is evil!
Trust me, I used to be from the government, and I am here to help.
