Answer:

y = 16, don't know if I'm 100% right but hope this helps.

Step-by-step explanation:

since they both equal Y they may be equal to each other

Then you would subtract 2x from both sides canceling it out on one side

2x + 8 = 5x - 4

-2x         -2x

This would make the equation 8 = 3x - 4

next you add the 4 from both sides

8  = 3x - 4

+4         +4

This will leave you with 12 = 3x

now you divide 3 from both sides and 12/3 = 4 makes X = 4

next you take (4) and plug it in to one of the equations

y = 2(4) + 8

y = 8 + 8

y = 16

Artyom0805 [142]
The value of x
5x+15+17(sides)=45(perimeter of sides/sum of sides)
5x+32=45
5x=45-32
5x=13
x=13/5
x=2.6
The value of x is 2.6

Jamey says she only has 30% of her book to go before she finishes it. she has read 147 pages so far
Lubov Fominskaja [6]
Let's just change your problem to 147 of 30% 

"Of" is always equaling to multiplication (×)

Now, it would be easier to simplify 

30% (147)
30% ÷ 100 = 0.3
0.3(147)
Now, we get to your answer which might be 44.1
