3u - 5u= - 2u=====
2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
add 8 and 2 then take away 3. even u should get 7u.

6t -2t + 5u = 4t - 5u
3u - 5u= - 2u=====
2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
7u.
7U and 10U - 35ft.
10u7 - 45u6 + 45u5 = 5u5 (2u2 - 9u + 9) = 5u5 (2u - 3) (u - 3)
add 8 and 2 then take away 3. even u should get 7u.

(9 - 5u)(9 + 5u)
Do you mean 5u-10 = u+46? If so then:- 5u-10 = u+46 5u-u = 46+10 4u = 56 u = 14
