Question

Two times a number added to 20 is same as 3 times number subtracted from 30. What is the number

Answer 1

Answer:

2x+30=90-3x

1. Combine like terms

**Remember, whatever you do to one side, you must do to the other.

2. Add 3x to both sides

2x+30=90-3x

+3x +3x

3. Subtract 30 from both sides

5x+30=90

-30 -30

4. Divide both sides by 5

5x=60

X=12

Check your answer

2×12=24

24+30=54

90-(12×3)

90-36=54

Answer 2

Question: Two times a number added to 20 is same as 3 times that number subtracted from 30 .What is the number.

Answer: The number is 2 .

Step by step explanation :

Let the number be x

According to the question,the equation formed is :

20 + 2x = 30 - 3x

2x + 3x = 30 - 20

5x = 10

x = $\huge{\frac{10}{5}}$

x = 2 .

Hence the number is 2 .

Verification of the answer:

20 + 2x = 30 - 3x

20 + 2 × 2 = 30 - 3 × 2

20 + 4 = 30 - 6

24 = 24

Verified.
