I just want to make sure I have the answer right. The problem is:
5 (x - 2) -2x + 1
----------------------
3
The line obviously means the whole top part is divided by 3. Thank you!!

Thank you guys so much, I got it right!! how about
4x-5y=20 solve for y
My answer doesn't really make sense!

top: 5x-10-2x+1
=3x-9
=3(x-3)
bottom: 3
therefore answer x-3
4x-5y=20
add 5y-20 to both sides
4x-20=5y
divide through by 5
y=4x/5-4
=4(x/5-1)

That's:
5/3(x-2) - 2/3 x + 1/3
=5/3 x - 10/3 - 2/3 x + 1/3
=(5/3 - 2/3)x -10/3 + 1/3
= 3/3 x - 9/3
= x - 3

[5(x - 2) -2x + 1] / 3
= [5x - 10 - 2x + 1] / 3
= [3x - 9] / 3
= 3[x - 3]/3
= [x - 3]

Expand it first
(5x - 10 - 2x + 1)/3
collect like terms
(3x - 9)/3
divide by 3
x - 3

(5(x-2)-2x+1)/3
(5x-10-2x+1)/3
(3x-9)/3
=(x-3) (that's your first answer)
now for the 2nd:
4x-5y=20
-5y =-4x+20
5y =4x-20
y =(4x-20)/5
y =4/5x-4)
therefore y=4/5x - 4
hope this helped!!

5(x-2)- 2x + 1/ 3
5x - 10 - 2x + 1 / 3
5x - 2x - 10 + 1/3
5x - 2x / 3 = 10 - 1/ 3
3x / 3 = 9 / 3
3x = 9*3/3
3x = 9
x = 9 / 3
= 3

3a + a/2 Multiply both terms by 2 to get rid of the fraction. 6a + a = 7a Or are you trying to solve fo a? In which case you would continue on from 6a + a = 0 7a = 0 a = 0/7 a = 0 Is the question (3a+2)/2 or (3a)+(a/2)??? My answer is correct for (3a)+(a/2).
