Jennifer has 14 marbles

For this case we must find the number of marbles that Jennifer has.

Let T be the variable that determines the number of total marbles that Jennifer has.

Let x be the variable that represents the number of red marbles that Jennifer has. So, [tex]x = 7[/tex]

Let y, the variable that represents the number of marbles blues Jennifer has. So, [tex]y = 7[/tex]

To find the value of T, we must add the variables x and y.

So, [tex]T = x + y[/tex]

[tex]T = x + y[/tex]

[tex]T = 7 + 7\\T = 14[/tex]

So, Jennifer has 14 marbles.
