In order to eliminate the y term, you need to find what y is equal to in the equation.
1. 6x-5y=-4
-5y=-4-6x
Y=6/5x+4/5
You then sub in 6/5x+4/5 in for y in the equation
2. 4x+2y=28
2y=-4x+28
Y=-2x+14
Hope this helps!
The total worth of the 4 pounds and 8 ounces of box is $1800
<h3>Total cost</h3>
Weight of the boxes:
- 4 pounds
- 8 ounces
- Cost of each pound = $400
Convert ounces to pounds:
8 ounces to pounds = 0.5 pounds
Total cost of the boxes = 4 pounds (400) + 0.5 pounds (400)
= 1600 + 200
= $1,800
