Question

Elias is 6 years older than Marcos. Together they are 42 years old. Let e repr equations represents this situation? m = e + 6 e + m = 42 O e = m - 6 e + m = 42 O e = m + 6 e + m = 42

Answer 1

Elias is 6 years older than Marcos

This can be interpreted as: e = m + 6

Together they are 42 years old

This can be interpreted as: e + m = 42

The answer is

e = m + 6

e + m = 42

Solving the equations, we have

e = m + 6

e + m = 42

Substitute e = m + 6 into the second equation

m + 6 + m = 42

2m + 6 = 42

2m=42-6

2m = 36

m=36/2

m=18

Substitute m = 18 into the first equation

e = m + 6

e = 18 + 6

e = 24
