Question

Is 3 a solution to the equation 6x-7=12?

Answer 1

No, 3 is not the solution. This is because if you were to plug 3 in for x, then he equation would be:
6(3)-7=12
Which is not true.
Because 6x3=18
And 18-7=11
Not 12.

Answer 2

3 is not the solution

The solution of given expression is

x = 19/6

Explanation:

It is given an expression in variable x,

6x - 7 = 12

To find the solution of given expression

Le the given expression be 6x - 7 = 12

6x = 12 + 7

6x = 19

x = 19/6

Therefore the solution given expression is 19/6

So 3 is not the solution
