The number is 4.
The work:
3x-7+5x=25
8x=32
x=4

x= the number you are tryin to fine
3x-7+5x=25
add the 3x and 5x-->8x
8x-7=25
add the 7 on both sides
8x=32
divide both sides by 8
x=4

Well angelina let us express this as a formula

8x=32
x=4
The number is 4

If your order of operations is worded properly in your question then...
3x - 7 + 5x = 25
Solve for x.
so 8x = 32
x = 4
Isn't algebra wonderful!

the answer is 4, the equation is 3x-7+5x=25, but you really need to do your homework yourself. I just had to do mine, and I'm in algebra too.

First, write it out in a mathematical formula...
3x-7+5x=25
OR, if the two x's are different numbers...
3a-7+5b=25
AND THEN... Solve it yourself!

3X+5X=32
X=4
