Select all the equations where c=9 is a solution choose 2 answers a. 4-c=5 b. 20=14+c c. 15=c-6 d. c divided by 3=3

we are given

c=9  is a solution

we will select each options and then verify it

option-A:

Subtract both sides 4

Multiply both sides by -1

so, this is FALSE

option-B:

Subtract both sides by 14

so, this is FALSE

option-C:

Add both sides by 6

so, this is FALSE

option-D:

Multiply both sides by 3

so, this is TRUE
