Verified Answer :

c=carlo=13
x=sister


carlos (13) is (=) 5 years older (5+) twice sisters age (2 times x)
13=5+2x
mius 5 both sides
13-5=5-5+2x
8=0+2x
8=2x
divide both sides by 2
4=x

2x+5=13
x=4

Answer:

\(2x+5=13\)

x=4

Step-by-step explanation:

Carlos is five years older than twice his sister's age. carlos is 13.

Let x represents the sister's age

Carlos age = twice of sisters age plus 5 years

twice of sister's age means 2 times sister's age

Carlos age = \(2x+5\)

Now Carlos age is 13

So the equation is \(13= 2x+5\)

Now we solve for x to find the solution

\(2x+5=13\)

Subtract 5 from both sides

\(2x=8\)

Divide both sides by 2

\(x=4\)
