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

Samuel is 18

Yvonne is 22

Step-by-step explanation:

So let y represent yvonne and s as samuel

Let's set-up two equations

y + s = 40

y + 4 = s

So since s = y + 4 lets substitute

y + (y + 4) = 40 which gives us;

y + y + 4 = 40

Collect like terms;

2y + 4 = 40

Subtract 4 from both sides

2y = 36

Divide both sides by 2

y = 18

y + 4 = 18 + 4 = 22

So yvonne is 22 years of age

40 - 22 = 18

So Samuel is 18 years of age
