Solve simultaneously:
<span>15x-8y=52 and
6x+14y=38
</span>
Let's solve this system thru elimination by addition/subtraction:
Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get
-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:
258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.

From the problem statement, the population of South Africa is four times the population of Greece.
The population of Greece is 11 million
<em>Given data</em>
Population of South Africa is 44 million,
Let the population of Greece be x
Hence the population of South Africa will be = 4*x
Hence the expression becomes
44million = 4x
Let us divide both side by 4 to find the population of Greece
x= 44million/4
x = 11 million
Hence the population of Greece is 11 million
