I'll solve the first equation and let you solve the second equation
-3=(-6+x)/2
-3*2 = -6+x ... Multiply both sides by 2.
-6 = -6 + x
-6 + 6 = -6 + x + 6 ... Add 6 to both sides.
0 = 0 + x
0 = x
x = 0
So the solution to -3=(-6+x)/2 is x = 0

okay so basically
-10=-3+y
-13=y
am i correct?
jimthompson5910 (jim_thompson5910):
-10 = -3 + y is correct
jimthompson5910 (jim_thompson5910):
but when you solve -10 = -3 + y for y, you won't get y = -13
jimthompson5910 (jim_thompson5910):
-10 = -3 + y
-3 + y = -10
y = -10 + 3
y = ???

oh yeah forgot. -7
jimthompson5910 (jim_thompson5910):
correct, y = -7

okay but when u said multiply by both sides, u only multiplied one side?
jimthompson5910 (jim_thompson5910):
when you multiply (-6+x)/2 by 2, the 2 in the denominator will cancel
