Heya Mate
We need to find the value of variable over here
A ) 6 x = 12
→ x = 2
[ since , Transposing constant from Left to right , Opression is changed from Multiply to Division ]
B ) 3n = 9
→ n = 3
[ Opression is changed from Multiply to Division ]
C ) 11t = 23
→ t = 11.5
D ) 36 = 9k
→ 9k = 36
→ k = 4
Hope this helps you
