4

Step-by-step explanation: 4

if the required number is 'x', then the sum of 2 times the number and 10 is 2x+10; the difference of the number and 1 is x-1. Using these two equation it is possible to make up the common one:

2x+10=6(x-1);

4x=16;

x=4

if you mean

then it's c. 8, -7/3

but if you mean

then it is
