Answer:

2

Step-by-step explanation:

2u+10=22+u

or,2u-u=22-10

or, u=2____1

Answer:

u = 12

Step-by-step explanation:

2u + 10 = 22 + u

Shift the u on the right side to the left side, changing the + to -.

2u - u + 10 = 22

Simplify 2u - u

u + 10 = 22

Minus 10 from both sides.

u = 12

Checking:

2(12) + 10 = 22 + 12

24 + 10 = 34

34 = 34
