Greeting homo sapien. I'm assuming you're trying to find the number of giraffes. First we got to establish the variables.
X = # of giraffes
Y = # of elephants
Now let's write the equations
Equation #1
Y = 3X + 4
Now I'm also assuming you meant to write there are 23 more elephants than giraffes, so it would look like this.
Y = X + 23
Now just substitute Y's so you creat an equation with X being the only variable.
X + 23 = 3X + 4
Simplify
2X = 19
X = 9.5
So APPARENTLY there are 9.5 giraffes.... not sure how to get half a giraffe buuuuuuuuut oh well.
