Let X = number of Giraffes
Number of elephants = 3X - 4
Because it was stated that there are more than 23 elephants, the number should not fall below 23.
The algebraic expression would be:
3X - 4 = 23
To get X; Transfer -4 to the other side, changing its sign to positive.
3X = 23 + 4
3X = 27
To get X; Divide both sides by 3
X = 27 / 3
X = 9
Since X represents the number of giraffes, then, there are 9 giraffes in the zoo.
To Check: Substitute X with 9 in the algebraic expression.
3X - 4 = 23
3(9) - 4 = 23
27 - 4 = 23
23 = 23 EQUAL
Yes, because 23 hundreds is 23,000 and 7 tens is 70 and 5 ones is 5
45x3 is 135. And then when you square 135 you would get 18,225
Answer:

Step-by-step explanation:
How am I supposed to write it like $279=9 Tickets?
Answer:
None
Step-by-step explanation:
We can eliminate the x's by add the 2 equations :
2y = 18
Divide both sides by 2 :
y = 9
Substitute this value into equation 1 to solve for x :
-3x + (9) = 6
Subtract 9 from both sides :
-3x = -3
Divide both sides by -3 :
x = 1
Substitute these values into equation 2 to check :
-3(1) + 6 = 12 ❌❌
So it has no solution
