To Find:

We have to find the value of x.

Solution:

This is a problem of finding x.

Let us tackle this question.

We can solve this problem by using the following process.

According to the question,

-7x + 2×7 (5) = -7 (10)

⇒-7x + 2 × 35 = -70

Answer 2

Step-by-step explanation:

1] -7x + 2 × 7(5) = -7(10)

2] -7x + 2 × 35 = -70

3] -7x + 70 = -70

4] -7x = -70/70

5] -7x = -140

6] x = -140/7

7] x = 20

hence

I hope that now you are clear with our doubt
