Hey! This can look pretty confusing but, don’t worry I’m here to help! I actually just studied these.

So basically you’re wanting to solve for Y.
You can calculate this by cross multiplying and the answer to your question is 12.

I know how it is when you need help and you just can’t grasp something, so if you have absolutely anymore questions or concerns, post em in chat and I’ll be happy to try to answer.
Have a great evening and I hope this helped!

Answer:

4b+8 = 20

---------------

4b = 20

-------------------

b = 5

Step-by-step explanation:

We need to solve for b in the following equation:

\frac{4b + 8}{2}  = 10

When we multiply each term by 2 the denominator cancels out:

\displaystyle 2 \times \frac{4b + 8}{2}  = 10 \times 2\\\\4b + 8 = 20

Next, we subtract 8:

4b +8 - 8 = 20 - 8\\4b = 20

Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term

\displaystyle 4b = 20\\\\\frac{4b}{4} = \frac{20}{4}\\\\b = 5
