The total age of yvonne and samuel is 40 yvonne is 4 years older than samuel find their ages.

Yvonne is 22

Samuel is 18

Step-by-step explanation:

y is age of yvone, s is age of samuel

Write 2 equations:

y + s = 40

y = s + 4

Substitute (s + 4) into y in the first equation:

s + 4 + s = 40

Solve:

2s + 4 = 40

2s = 36

s = 18

Substitute 18 for s in either equation:

y + 18 = 40

Solve:

y = 22

24+x=y
