Answer 2

Answer:

Step-by-step explanation:

(A) The given equation is:

$2c+5(c-5)=10$

Upon solving the above equation, we get

$2c+5c-25=10$

$7c=35$

$c=5$

Thus, the value of c is 5 and the option (C) is correct.

(B) The given expression is:

$4x-8-4x=9$

Upon solving the above equation, we get

$-8=9$

which is not possible, therefore there are zero solution of the given equation.

Hence, option (A) is correct.

(C) The given equation is:

$3(4x+5)=12$

Upon solving the above equation, we get

Step 1. $12x+15=12$

Step 2 $12x=-3$

Thus, option A is correct.

(D) The given equation is:

$3y-8=22$

Upon solving the above equation, we get

⇒$3y=30$

⇒$y=10$

Hence, option (C) is correct.

(E) The given equation is:

⇒$2(3y-6)=0$

⇒$6y-12=0$

⇒$6y=12$

⇒$y=2$

Hence, option C is correct.
