-15 - (-3) + 6

-15 - (-3) = -15 + 3 = 3 - 15 = - 12

-12 + 6 = 6 - 12 = -6

Your answer is -6

-15-(-3)+6 = -6
so your answer is
-6

How do i solve x/2+1/3=x/3+1/2

Answers

x/2+1/3=x/3+1/2
x/2=x/3+1/2-1/3
x/2 - x/3 = 3/6 - 2/6
x/2 - x/3 = 1/6
3x/6 - 2x/6 = 1/6
x/6 = 1/6
x = 1/6 * 6

x = 1

$(1)/(2)x + (1)/(3) = (1)/(3)x + (1)/(2) \n(1)/(6)x + (1)/(3) = (1)/(2) \n(1)/(6)x = (1)/(6) \n6((1)/(6)x) = 6((1)/(6)) \nx = 1$
