Question

1. What is the solution for 2x-5=7

O x = 6
O x = -6
X = 12
O x = 9

Answer 1

Given, equation in the question which we have to solve is

`2x - 5 = 7`

Here, we need to find x. So, Let's isolate x on one side of the equation. It is present in the left hand side. Add 5 to both sides,

`2x - 5 + 5 = 7 + 5`

`2x = 12`

Divide 2 from both sides,

`(2x)/(2) = (12)/(2)`

`x = 6`

So, the correct option is A.
