Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
Answer:
p = -4
Step-by-step explanation:
So first of all, you need to combine like terms. In order for that to happen, you need the like terms on one side. You get rid of a number by adding ( if subtraction), multiplying (if division), and subtracting (if addition) by its reciprical. Since it is a negative 3, you add it. Whatever you do to one side, you have to do to the other. That leaves us to 4p = 9 + 7p +3 or 4p = 12 + 7p. Since 7p is positive, you have to subtract from both side leaving us with 4p - 7p = 12 or -3p = 12. You then divide both sides with -3 to isolate the variable leaving us with p = -4
