Answer:

Greg is 67 years old.

Step-by-step explanation:

John = 2 * B

G = 7 + B

J - 4 + B - 4 + G - 4 = 55

J + B + G = 67

2B + B + 7 + B = 67


4B = 60

B = 15

J = 30

G = 22

30 + 15 + 22 = 67

67 = 67

5. -2 = p - 1<br> Help me pleaseee
dangina [55]
Assuming you are trying to find the value of p:

You would add 1 to each side to make the p alone

-2 =p - 1
+1 +1

-1 = p


To check, you can put p in the original equation

-2 = -1 - 1

-2 = -2 which means this is correct


Hope this helps! If you can, please give brainlist! :)
