2x + 9 = 15
you move + 9 to the other side of the equation, you will get:
2x = 15 - 9

Step-by-step explanation:
Let x be mother + children = 18
Father's age = 38
Average age of the family = 14
38 + 18x /( x + 1 )= 14
Opening the bracket
38 + 18x = 14x + 14
Collecting like terms
24 = 4x
x = 6
no of children in the family is 6.

Answer:
2.5 pounds
Step-by-step explanation:
Let s represent the number of pounds of dried strawberries that should be added to the bananas. The total cost of the mixture will be ...
(2.50)(3) +(8.00)(s) = (5.00)(3 +s)
7.50 +8s = 15 +5s . . . . . . . eliminate parentheses
3s = 7.50 . . . . . . . . . subtract 7.50+5s
s = 2.50 . . . . . . divide by 3
2.5 pounds of dried strawberries should be added to make the mixture.
