Answer:

u = 7

Explanation:

First do distributive property to 2(u+3) this makes it -15=-5u+2u+6.

Then combine like terms: -15= -3u +6 (the positive u's cancel out the negative u's)

get U by itself by subtracting 6 from both sides: -21= -3u

Divide both side by -3: -21/-3 = -3u/-3

Answer is 7= u

Check your answer: Plug in 7

-15 = -5(7)+ 2(7+3)

-15= -35 + 14+6

-15= -35+20

-15=-15
