Answer:
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.
