Question

Help me solve this equation! and please tell me how you did it step by step, please!!!

-3(2u+5)+3.5u=-1u

a.u=10
b.u=-10
c.u=4
d.u=-4


Please don't plug in the numbers! I'm really confused and I need help on how I could solve this step by step.

Answer 1

I got you!
First distribute.
-6u-15+3.5u=-1u
Add like terms
-2.5u-15=-1u
Get the u’s on one side and the regular number on the other
-1.5u=15
Divide
U=-10
