Step-by-step explanation:
take 6-2 to get 4
4 is your common difference for ex.
-6+4 = -2
-2+4=2
2+4=6. You have to two pick an easier numbers out of the problem to find your common difference. Then check your answer to make sure it is right.
if x=6.5, plug this value into the expression to test the inequality.
9-6.5 = 2.5
2.5 > 3
this statement is FALSE because 2.5 is less than 3 NOT greater than.
Answer:
7/11
7y +6+4y+13=26
firstly collect like terms
7y+4y+6+13=26
11y+19=26
11y=26-19
11y=7
then divide through by 11
y=7/11
