3u plus 1/10 when solved give the value of u = 1/30.
13u
7 + 4u = 70 - 3u[add 3u to both sides]7 + 4u + 3u = 70 - 3u + 3u7 + 7u = 70 + 07 + 7u = 707u = 70 - 77u = 63u = 9
U=2.
9
7u.
49
u = 7
Is 24u^2 + 35
2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
Add 3u to both sides. Subtract 7 from both sides. 7u = 63 u = 9
