It is given that,
The total cost of a skates and knee pads is $63.
Therefore, Total cost = cost of skates + cost of knee pads.
We know that, the cost of the skates is $45.
<u>To find the cost of the knee pads :</u>
Let 'x' be the cost of the knee pads.
The equation is framed with the variable 'x' that gives the cost of the knee pad.
The equation is 63 = 45 + x.
<u>To find the value of x :</u>
The first step is to subtract 45 from both sides of the equation.
⇒ 63-45 = 45+x-45
⇒ 18 = x
⇒ x = 18 dollars.
The cost of the knee pad is $18.
