Question

(simple algebra question for grade 6)

x + 10 = 30?

2n = 10

n + 3= 11

Answer 1

Answer:

1. x + 10 = 30

Answer

x = 30 - 10

x = 20.

2. 2n = 10

Answer

$2n = 10$

$n = \frac{10}{2}$

$n = 5$

3. n + 3 = 11

Answer

n = 11 - 3

n = 8

Hence we solved the Question.

Proving:-

1. We know that, 30 - 10 = 20. So, the answer is 20.

2. 5 × 2 = 10. So, the answer is 5.

3. We know that, 3 + 8 = 11 and 11 - 3 = 8. So, the answer is 8.

Hence, proved !!

Answer 2

Step-by-step explanation:

1. x + 10 = 30

x = 30-10

x = 20

Proving :

20 + 10 = 30

2. 2n = 10

n = 10/5

n = 5

Proving

2 × 5 = 10

3. n + 3 = 11

n = 11 - 3

n = 8

Proving

8 + 3 = 11

Hence all proved..
