Pat is 2 years younger than his wife, Wynn. Ten years ago the sum of their ages was 48. How old are they now?

Pat is 33 and Wynn is 35

Step-by-step explanation:

x for pat and y for wynn

Pat is 2 years younger than his wife : x-2=y

Ten years ago the sum of their ages was 48 : x+y=48

substitute x-2 for y in the second equation:

x+y=48

x+x-2=48

2x=46

x=23 age of Pat ten years ago and Wynn=25

now Pat is 33 and Wynn is 35

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
