!)If 2x(3y-2z=x+3,What is the value of z in terms of x and y.?
2)g(x)=1/x+3-2/x, what is the value of g(1/3)?

3)Sum of the square of p and square root of q is equal to the square of the difference of p and q
Which of the following expresson is equivalent to the given statement
A)√p+q2= (p-q)2
B)p2+√q=(p-q)2
C)(p+√q)2=(p-q) 2

4)The two numbers differ 1/3, and the sum of their numbers is s .Express the s in terms of the smaller number.
Solution: difference is =1/3Let the smaller of the number is x
Then the other number = x+1/3 (given the difference is 1/3)
Their sum s= smaller number + the bigger number
= x + (X+1/3) = x+x+1/3 =2x+1/3
=2x*3+1/3=6x+1/3

5)If m and n are odd integer.
Then which of the following are true.
A)(m-2)+(n+1) is even
B) (m+6) ÷(n+2) is odd
(m+3)×(2n) is odd

6)6)< ---------x3———————–x6————-x2—
In the above number line , Find the value of x
Solution: here x3< (x)2
It means that the value of x is negative
x6<(x)2 ( since 6 > 2)
X is fraction
To satisfy both the condition x is negative fraction
