4(2x+8)=10x+2-2x+30 what is x?
Anastaziya [24]

Let's solve your equation step-by-step.

4(2x+8)=10x+2−2x+30

Step 1: Simplify both sides of the equation.

4(2x+8)=10x+2−2x+30

(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)

8x+32=10x+2+−2x+30

8x+32=(10x+−2x)+(2+30)(Combine Like Terms)

8x+32=8x+32

8x+32=8x+32

Step 2: Subtract 8x from both sides.

8x+32−8x=8x+32−8x

32=32

Step 3: Subtract 32 from both sides.

32−32=32−32

0=0

Answer:

All real numbers are solutions.

agasfer [191]

Answer:

Semi-monthly gross pay = $662.5

Step-by-step explanation:

Given:

Earning per hour = $13.25

Number of hours per week = 25 hours

Find:

Semi-monthly gross pay

Computation:

Assume two week in semi-month

So,

Total working hour = 2(25)

Semi-monthly gross pay = Total working hour × Earning per hour

Semi-monthly gross pay = 50 × 13.25

Semi-monthly gross pay = $662.5
