Explanation:
Option 1.
4y=12
Dividing 4 both sides
y=3
Division property should be used.
Option 2.

Cross multiplying each other,
y=12(4)
y=48
Option 3.
2(4y)=12
Opening bracktet in LHS
8y=12
Dividing both sides by 8 i.e.

Division property is used.
Option 4.
y+4=12
Subtracting both sides by 4 i.e.
Y+4-4=12-4
y=8
Subtraction property is used.
<em><u>It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.</u></em>
Answer:
D
Explanation:
D is the only option where the cause of the pollution is not something man-made.
This is disproven by the study of cells due to plants don't grow food they making by using sunlight are and water and nutrients <em><u>from </u></em><em><u /></em><u />the soil so it cannot produce the soil due to this fact.
Riparian zones can reduce the impact of water pollution is true.
The statement is true.
<h3 /><h3>What are Riparian zones?</h3>
The areas along the banks of rivers and other sources of surface water are known as riparian zones.
The floodplain and riparian buffers bordering the floodplain are included.
Riparian zones benefit streams, groundwater, and downstream land areas in numerous ways, both environmentally and recreationally.
Thus, the given statement is true.
