2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
(9 - 5u)(9 + 5u)
If: -52 --3u = 8 then u = 20
No. It is a sum of four terms which can be simplified to a sum of three terms.

2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
(9 - 5u)(9 + 5u)
If: -52 --3u = 8 then u = 20
-5u + 4 + 8u = 43simplify by subtracting 4 from both sides of the equation to get rid of the 4 on the left:-5u + 8u = 43Simplify further by combining the -5u and the 8u:3u = 43Divide both sides by 3 to solve for u:u = 43/3rewrite the fraction:u = 14 1/3
No. It is a sum of four terms which can be simplified to a sum of three terms.

add 8 and 2 then take away 3. even u should get 7u.
Do you mean 5u-10 = u+46? If so then:- 5u-10 = u+46 5u-u = 46+10 4u = 56 u = 14
5u + 2 = -185u = -20u = -4
