Question

Ina writes the expression below. [x + 5) - (x - 5] What is the value of Ina's expression for x= 10?​

Answer 1

10

Explanation:

Given the expression below.

[x + 5) - (x - 5]

If x = 10, we will have to substitute x = 10 into the expression given as shown;

[x + 5) - (x - 5]

=[10 + 5) - (10 - 5]

= 15 - 5

= 10

Hence the required value is 10
