Equivalent equations are equations that have the same value

  • The simplified equation is: \(25q + 10d + 5n= 127\)
  • It is not possible to have exactly 60 pennies

The equation is given as:

\(25q + 10d + 5n + 60 = 187\)

(a) Simplify the equation

We have:

\(25q + 10d + 5n + 60 = 187\)

Subtract 60 from both sides of the equation

\(25q + 10d + 5n + 60 - 60= 187 - 60\)

Evaluate the like terms

\(25q + 10d + 5n= 127\)

Hence, the simplified equation is: \(25q + 10d + 5n= 127\)

(b) Having exactly 60 pennies

To have exactly 60 pennies in $1.87, then the simplified equation in (a) above must be true

However, the equation \(25q + 10d + 5n= 127\) is not true for whole values of q, d and n.

Hence, it is not possible to have exactly 60 pennies
