Step-by-step explanation:
The most common way to raise the pH of soil is to add pulverized limestone to the soil. Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate. These are called dolomitic limestone and calcitic limestone respectively.
The first one = 60.3 so it can’t be that one.
the second one = 34.5 so not that one either
the third one = 60.3
and the last one = 28.3
First divide both sides by - 5,

Move the constant to the right side of the equation and change its sign (-4 => +4)

Add the numbers,

Answer:
No solutions.
Step-by-step explanation:
x - y = 2 <Start with an equation
x - (x + 2) = 2 <Plug in the given y value and solve for x
x - x - 2 = 2 <Combine like terms
0 - 2 = 2 <There are no values of x
No solutions.
