Use the distribution property to get -5u+15=4u-3. Add 5u to both sides of the equation to get 15=9u-3. Add 3 to both sides of the equation to get 18=9u and then divide both sides of the equation by 9. This gives you u=2.
remember you can do anything to an equation as long as you do it to both sides
first, distribute
remember, negative times negative=positive
distributive proeprty is a(b+c)=ab+ac
so
-5(u-3)=4u-3
distribute
-5u+15=4u-3
add 5u to both sides
15=9u-3
add 3 to both sides
18=9u
divide both sides by 9
2=u
u=2
