(I'm going to solve this problem using the RESAC form).
R : x = Lilet's age; 3x = Margie's age
E : x + 15 + 3x + 15 = 38
S : x + 15 + 3x + 15 = 38
4x + 30 = 38
[tex] \frac{4x}{4} = \frac{8}{4} [/tex]
x = 2; 3x = 6
A : Margie is 6 years old while Lilet is 2 years old.
C : x + 15 + 3x + 15 = 38
2 + 15 + 3(2) + 15 = 38
2 + 15 + 6 + 15 = 38
17 + 21 = 38
38 = 38
R : x = Lilet's age; 3x = Margie's age
E : x + 15 + 3x + 15 = 38
S : x + 15 + 3x + 15 = 38
4x + 30 = 38
[tex] \frac{4x}{4} = \frac{8}{4} [/tex]
x = 2; 3x = 6
A : Margie is 6 years old while Lilet is 2 years old.
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
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.
