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
Answer:
n=-14
Step-by-step explanation:
2n+18-n=-10-n
n+18=-10-n
+n +n
2n+18=-10
-18 -18
2n=-28
/2 /2
n=-14
