The value of x so that the function has the given value k(x)=6x-12 becomes k(x)=18 is 5.
From the information that's given in the question, we are provided with the inequality that k(x)=6x-12; and k(x)=18.
In order to solve the question, one has to equate both equations to each other. This will be:
6x - 12 = 18
Collect like terms.
6x = 18 + 12
6x = 30
Divide both side by 6
6x/6 = 30/6
x = 5
k(x)=6x-12
k(x) = (6×5) - 12
k(x) = 30 - 12
k(x) = 18
Therefore, the value of x so that the function has the given value k(x)=6x-12 becomes k(x)=18 is 5
