i need the answer for my homework i have tryed to solve it and couldnt
12 - x = 4
You could subtract 4 from both sides of the equation, which will result in:
8 - x = 0
Then add an x to both sides of the equation to cancel out the negative values:
8 = x
The answer is x = 8.
First, multiply both sides of the equation by -1;
- 1 * (12-x) = - 1* (4)
-12+x = - 4
Now, rearrange so that x = -4 + 12 or
x = 8
Now, you can check your work by substitution 8 back into the original formula,
12-( +8) = 4
and since this is correct, it proves your solution
Subtract 12 from the 4. -x = -8 divide the -x (-1) into the -8. Answer is 8.
First subtract 12 on both sides to get -x= - 8 and then divide both sides by -1 to get x= 8
SUPER DUPER EASY :D
Minus 12 on each side leaving you with:
-x=-8
then for a positive x do:
(-x)-x = -8(-x)
which equals:
x=8
