Answer:

-13

Step-by-step explanation:

We remove the -4 by adding 4 to each side:

3y = -43 + 4

Now we simplify to give:

3y = -39

So now we divide both sides by 3 to give our answer of:

y = -39/3
y = -13
We can substitute this into the original equation to check our answer:

-4 + 3(-13) = -43

-4 + -39 = -43

8+35/w=15<br>a.8<br>b.6<br>c.10<br>d.5

RoseWind [281]

Answer:

$\boxed{ \bold{ \huge{ \bold{w = 5}}}}$

Option D is the correct option

Step-by-step explanation:

$\sf{8 + \frac{35}{w} = 15}$

⇒ $\sf{ \frac{8 \times w + 35}{w} = 15}$ { w ÷ 1 = w , So, I wrote 8 × w }

⇒ $\sf{ \frac{8w + 35}{w} = 15}$

Apply cross product property

⇒ $\sf{8w + 35 = 15w}$

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒ $\sf{8w - 15w = - 35}$

Collect like terms

⇒ $\sf{ - 7 w = - 35 }$

Divide both sides of the equation by -7

⇒ $\sf{ \frac{ - 7w}{ - 7} = \frac{ - 35}{ - 7} }$

Calculate

⇒ $\sf{w = 5}$

Hope I helped!
