Answer 1

Answer:

x + (x+2) = 30

Step-by-step explanation:

14 pennies and 16 nickels

Answer 2

Answer:

$x+x+2=30$

Step-by-step explanation:

Let the pennies be represented by = x

Let nickels be represented by = y

Mary Lou has 2 more nickels then pennies.

We get $y=x+2$

Also given that she has 30 coins all together.

$x+y=30$

Substituting y here, we get the requires equation as:

$x+x+2=30$

Now, solving this we will get the value of x.

$2x+2=30$

$2x=28$

x = 14

And $y=30-14=16$

So, there are 14 pennies and 16 nickels.
