Michael and Kathryn bowl together and their combined total score for one game was 425points. Michael’s score was 70 less than tw
ice Kathryn’s. What system of equations models the problem if x represents Kathryn’s score and y represents Michael’s score?
1 answer:
Hey there!
Let us take Michael's score as ' x '
Let us take Kathryn's score as ' y '
Michael - 70 less than twice Kathryn's
x = 2y - 70
y = y
Add them, we get , 425
2y - 70 + y = 425
3y - 70 = 425
3y = 495
y = 495/3
y = 165
Kathryn's score = 165
Michael - 2 ( 165 ) - 70
= 260
