Answer:
d
Step-by-step explanation:
Given
32cd = 11cd - 42 ( subtract 11cd from both sides )
21cd = - 42 ( divide both sides by 21 )
cd = - 2 → d
32cd = 11 cd − 42 : Subtract 11cd from both sides.
32cd = 11cd − 42
-11cd − 11cd
21c = −42
Divide both sides by 21.
21cd /21 = −42/21
cd = −2
32cd = 11cd − 42
-11cd − 11cd
21c = −42
Divide both sides by 21.
21cd /21 = −42/21
cd = −2
