Question

The equation given by x – 4 = -2 has a solution:
$
  {\text{A}}{\text{. 6}} \\
  {\text{B}}{\text{. 2}} \\
  {\text{C}}{\text{. 4}} \\
  {\text{D}}{\text{. 1}} \\
$

Answer 1

Hint – Keep the variable term only to the one side of the equal to sign and try to make its coefficient equal to one , the term we get on the other side of equal to sign will be its solution.

Complete step-by-step answer:
Given Data,
x – 4 = -2

Adding 4 to both sides
⟹x = -2 + 4
⟹x = 2
The solution of the equation given by x – 4 = -2 is x = 2.

Hence Option B is the correct answer.

Note – The key in solving such types of problems is to directly simplify the given equation to find the value of x. In case the equation is not as straightforward, we could also substitute the values of all the given choices in the given equation to find its solution.
