You x Value = 5!

Answer 2

Answer: The value of x = 5.

Explanation:

Given linear equation is 12-x=7 with variable x

To find the solution i.e. the value of x of the given linear equation, we need to perform following steps:

Step 1. Subtracting 12 from the both sides of the equation,we get

⇒12-x-12=7-12

⇒-x=-5

Step 2. Multiplying (-1) on the both sides ,we get

⇒-x × -1=-5 × -1

⇒x=5

So ,the value of x=5

Thus required solution of the given linear equation is x=5.
