R : x = Lilet's age; 3x = Margie's age

x = 2; 3x = 6

C : x + 15 + 3x + 15 = 38

2 + 15 + 3(2) + 15 = 38

2 + 15 + 6 + 15 = 38

17 + 21 = 38

38 = 38

Margie=M

Lilet=L

M=3L

M+15+L+15=38

Add like terms

M+L+30=38

Subtract both sides by 30

M+L=8

Substitute the value of L

3L+L=8

Add like terms again

4L=8

Divide both sides by 4

L=2.

Now lilet is 2 years old now substitute lilet's age to the equation

M=3L

M=3(2)

M=6

Hope this helps

Lilet=L
