Solution:
2/x + y/4 = 3/2
Let's solve for y.
2/ x + y/ 4 = 3/ 2
Step 1: Multiply both sides by 4x.
xy + 8 = 6x
Step 2: Add -8 to both sides.
xy + 8 + − 8 = 6x + −8
xy = 6x − 8
Step 3: Divide both sides by x.
xy/x = 6x - 8/x
Answer =====> y = 6x - 8/x
When Graph:
y = 6 - 8/x
x- Intercepts Points:
4/3, and 0
Equation====> 2:
Let's solve for x.
2/ x + y/ 4 = 3/ 2
Step 1: Multiply both sides by 4x.
xy + 8 = 6x
Step 2: Add -6x to both sides.
xy + 8 + − 6x = 6x + − 6x
xy − 6x + 8 = 0
Step 3: Add -8 to both sides.
xy − 6x + 8 + − 8 = 0 + −8
xy − 6x = −8
Step 4: Factor out variable x.
x(y − 6) = −8
Step 5: Divide both sides by y-6.
x( y - 6 )/y - 6 = -8/ y - 6
Answer ======> x = -8/y - 6
Hope that helps!!!! : )

Answer:
2 bags of topsoil.
Step-by-step explanation:
The attached figure shows a flower bed.
One bag of topsoil covers 15 square meters.
We need to find how many bags of topsoil does Tom need to cover his flower bed.
The area of the flower bed is :
Let he has to cover x bags of topsoil. So,
x = Area of flower bed/Area of 1 bag of top soil
x = 30/15
x = 2
Hence, he will need 2 bags of topsoil to cover his flower bed.
