Answer:

number is n =2

Step-by-step explanation:

Let the number be n

According to the information given in the question we have following relation

Twice the number is 2n

18 less the number mean n- 18

Sum of two relation is equal to difference btween -10 and number n. therefore we have

2n + (n-18) = -10 -n solving above equation for n we have

4n = 8

n =2
