Problem:

Solution:

let the expression

-10a -9n + 16-30 + 3n + 15 a + 50 + a =

Putting together similar terms we have

(-10a +15a+a) + (-9n+3n ) + (16-30+50) =

this is equivalent to:

(6a) + (-6n) + (36)

this is equivalent to

6a -6n+36

then, the correct answer is:

6a -6n+36

Answer:  \bold{w=\dfrac{6y-3}{2}}

<u>Step-by-step explanation:</u>

Isolate w by performing the following steps

  • Multiply by 6 on both sides to clear the denominator
  • Subtract 3 from both sides
  • Divide both sides by 2

y=\dfrac{1}{2}+\dfrac{w}{3}\\\\\\6\bigg[y=\dfrac{1}{2}+\dfrac{w}{3}\bigg]\quad \implies \quad 6y=3+2w\\\\\\6y-3=3-3+2w\quad \implies \quad 6y-3=2w\\\\\\\dfrac{6y-3}{2}=\dfrac{2w}{2}\quad \implies \quad \large\boxed{\dfrac{6y-3}{2}=w}
