Question

Gary is 3 years older than twice the age of his sister (Elena) __________.

Which shows an equation for this situation
A) G=6E
B) G=2E+3
C) E=3G+2
D) G=3G+2

Answer 1

The first thing we must do for this case is to define variables.

We have then:

G: Gary's age

E: Elena's age

We then have the following expression:

Gary is 3 years older than twice the age of his sister (Elena):

Using the defined variables, we can write the expression as:

G = 2E + 3

Answer:

an equation for this situation is:

B) G = 2E + 3

Answer 2

The equation shows this situation is Option (B) .

i.e G=2E+3

Reason

As given

Gary is 3 years older than twice the age of his sister (Elena) .

Let us assume that the age of the Gary be G.

Let us assume that the age of the Elena be E.

Than the equation becomes

E = 2G + 3

Therefore option (B) is correct .
