Given that 3(x-c)=2x+5 where c is an integer, shoe that x cannot be a multiple of 6
olga nikolaevna [1]

Answer:

The explanation in the procedure

Step-by-step explanation:

we have

3(x-c)=2x+5

solve for c

3x-3c=2x+5

3c=3x-2x-5

3c=x-5

c=(x-5)/3

For x=6 -----> Find the value of c

c=(6-5)/3=1/3 ------> is not an integer

therefore

x cannot be a multiple of 6
