7+3x-12x=3x+1
We will first make all the numbers which have x in go to the left.
So 7+3x-12x-3x, we make the 3x negative since to make it move it needs to change.
Then we will make all the sevens go to the right, so 3x-12x-3x=1-7.
So now it is much easier to figure out.
-12x=-6
If you would like to evaluate u + xy, you can do this using the following steps:
u = 18, x = 10, y = 8
u + xy = 18 + 10 * 8 = 18 + 80 = 98
The correct result would be C. 98.
