Step-by-step explanation:
Lets check step by step.
(a)2/3+c = 2/3
2/3+3c/3= 2/3
2+3c = 2 (when denominator are same they can be cancelled )
3c = 0
c =0
therefore no
b) 15x=3
x = 3/15
x= 1/5
therefore no
c) -1/6 + w = 1/6
-1/6 + 6w/6 = 1=6
-1 + 6w = 1 (when denominator are same they can be cancelled )
6w= 2
w = 2/6
w= 1/3.
therefore yes.
d) z/3= -1/9
z = -1/9×3
z=-1/3
therefore no
