hint Hint:

Hint:

Linear equation is an equation whose degree is one.

The correct answer is: 2.5

Explanation:

We have given an equation a(x + b) = 4x + 10. And has infinite solution

We have to find the value of b

Step 1 of 1:
The given equation is a(x + b) = 4x + 10
If it has infinite solution, it means it is true for all real x
So,
ax + ab = 4x + 10
ax = 4x
a = 4
And
ab = 10
4b = 10
b = 2.5
Hence, The value of b is 2.5 .
