Answer = £44,918
220x8.8 = 1936
2.3x2.1 = 4.83
1936 + 4.83 = 1940.83
1940.83/1.6 = 1213.01
1214x37 = 44918
So these are our two equations:
Before we can use elimination, subtract y on both sides of the first equation:
Now we are able to use elimination. To eliminate the y variable, add the two equations together to get . From here we can solve for x.
For this, just divide both sides by 3 and your first answer will be
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, x = 3 and y = 6.</u>
Divide 4 by 1, you get 4. Divide 120 by 4, get 30. Hope this helped!
