12-(x+3)=10
12 - x - 3 =10
9 - x = 10 subtract 9 from both sides.
-x =10 - 9
-x = 1 multiply both sides by -1
x = - 1
+206 To solve this you would have to first distribute the 12 to the x and the number three.
12 - (x + 3) = 10
12x + 36 = 10
Then use inverse operations to solve:
12x + 36 - 36 = 10 - 36
12x = -26
12x/12 = -26/12
x = -2.1666666666666667
I'm currently learning this so this is most likely incorrect. If you put this equation in the calculator you will get:
12 - (x + 3) = 10 = x=-1
