u=5/4
Step-by-step explanation:
distribute and simplify right side of equation
3= 28−14u −6u
3=28−20u
subtract 28 from both sides
3−28=−20u
−25=−20u
divide both sides by
−20/ −25 = u ⇒ u =54
Answer:
5/4
, open the bracket
3=28-14u-6u
Collect like terms
3-28=-14u-6u
-25 =-20u
Divide both side by -20
u=-25/-20. Minus sign will cancel each other and reduce to the lowest term
