Kara’s golf score was 1 less than three fourths of greg’s golf score. If the sum of their scores was 153, find Kara’s golf score.

Answer 1

X is mikes score

3/4x - 1 is Karas score

we add them to get 153

x + 3/4x - 1 = 153 multiply everything by 4

4x + 3x - 4 = 612

now solve

I get Kara 65

Answer 2

Well if k, g are the two golf scores :

k = 0.75g - 1 (1)

and

k + g = 153. (2)

You need k.

So rearrange (1) so you have g = .....

Then substitute this expression for g in (2)

And solve for (k).
