Question

a) x-3=-8=? b) 2x+4=-20-x=? c) -4x=+36=? d) x:(-3)=-1=?
e) 18:(-x)=-9=?

Answer 1

a) x-3 = -8
   x = -8+3
   x = -5

b) 2x+4 = -20-x
   2x+x = -20-4
   3x = -24
   x = -8

c) -4x = 36
    x = -9

d) x:(-3) = -1
   x = (-1)·(-3)
   x = 3

e) 18:(-x) = -9
   -x = 18:(-9)
   -x = -2
    x = 2
