Rahul use addition property of equality in step 2.
Solution:
The image of the question is attached below.
Step 1:
combine like terms together.
To make the denominator same multiply and divide 2x by 5.
Step 2:
By addition property of equality, add 
on both side of the equation.
Step 3:
Step 4:
Multiply by 
on both side of the equation.
Hence Rahul use addition property of equality in step 2.
Answer:
y=8/7x+5
Step-by-step explanation:
y=mx+b but m is your slope and b is your y intercept.
Answer:
yes, no, no
Step-by-step explanation:
For odd functions : −f(x) = f(−x) for all x
For even functions :f(x) = f(−x) for all x
1) -f(x)= -2x^3 -2x
f(-x) = -2x^3-2x
yes
2 ) f(-x) = 5x^3 -4 ≠ f(x)
no
3 ) f(-x) = -4x -4 ≠ f(x)
no
