You start sorting the terms. For instance, the x's go left, and the numbers go right. Remember that if you move something to the other side, the sign flips.

So lets move the x to the left and the +12 to the right:

5x-x = -4-12

Now we simplify

4x = -16

x = -4

done.

5x + 12 = x - 4
-12 -12
5x = x - 16
-x -x
4x = -16
4x = -16
___   ___ 4x & 4 cancel each other out so you are left with x & -16/4 which
4    4 equals x= -4

Step-by-step explanation:

Hey user☺☺

Option a is correct

Because the graph has only one solution.

As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.

Hope this will help☺☺
