Answer:
Sally is 63
Step-by-step explanation:
Represent Sally's age by x and Sam's by y.
Then x = 3y and x + y = 84.
Substituting 3y for x in the second equation, we get:
3y + y = 84, or 4y = 84, or y = 21. Since Sally is 3 times as old as Sam, we multiply 21 by 3: Sally's age is 3(21 years) = 63 years
Answer:
6
Step-by-step explanation:
To solve for x you must isolate it.
3x-2=2x+4
-2x -2x Subtract 2x from both sides
x-2=4 Your left with this
+2 +2 Then add 2 to both sides
x=6 x equals to 6
72/3 is 24 so 24+24+24 if you add one to one and take one away it’s the same so it becomes 23+24+25=72.
