2u+10=22+u

2

Step-by-step explanation:

2u+10=22+u

or,2u-u=22-10

or, u=21

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

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
