There are bricks of silver and bricks of gold. when 5 silver bricks and 2 gold bricks are placed on a scale, the weight is 119 ounces. when 4 silver bricks and 11 gold bricks are placed a scale the weight is 302 ounces. how much does each one weigh?

The weight of one gold brick is 15 ounces and the weight of one silver brick is 22 ounces.

Step-by-step explanation:

Given,

Weight of 5 silver bricks and 2 gold bricks = 119 ounces.

And Weight of 4 silver bricks and 11 gold bricks = 302 ounces.

We have to find out weight of each type of brick.

Solution,

Let the weight of 1 silver brick be x.

And the weight of 1 gold brick be y.

Since the weight of 5 silver bricks and 2 gold bricks is 119 ounces.

So we can frame it in equation as;

Again,

The weight of 4 silver bricks and 11 gold bricks is 302 ounces.

So we can frame it in equation as;

Now, multiplying equation 1 by 4 and equation 2 by 5 we get;

Now subtract equation 3 from equation 4, we get;

On substituting yhe value of y in equation 1, we get;

Thus the weight of one gold brick is 15 ounces and the weight of one silver brick is 22 ounces.
