Question

Cam is 3 years older than Lara, If there combined age is 63, determine their ages by solving simultaneous elmination.

Answer 1

Answer:

30 and 33 years

Step-by-step explanation:

Let Lara be x years

Cam =x+3

x+x+3=63

2x+3=63

2x=63-3

2x=60

x=60/2

x=30

Lara=30years and Cam =30+3+33years

Answer 2

Answer:

Lara 30 years, Cam 33 years

Step-by-step explanation:

denote x being the age of Lara

denote y being the age of Cam

Cam is 3 years older than Lara, so

y = x + 3

their combined age is 63 so

x + y = 63.

solving can be done by plugging in y = x+3, then

x + (x+3) = 63, which gives x = 30.

So Lara is 30 years.

Cam is 3 years older, so Cam is 33 years
