Michael and kathryn bowl together and their combined total score for one game was 425points. michael’s score was 70 less than twice kathryn’s. what system of equations models the problem if x represents kathryn’s score and y represents michael’s score?

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

Hope it helps!
