If y=x+2x−1, then the expression for x in terms of y is
If x+y=31/2 x-y= 21/2
Then the expression 8xy(x2 + y2) has the value ?
Which of the following is a linear expression ?
a) x2×y+xy+1
b) x+y+1
c) x3×y+xy+1
d) 4x2+1
b) 2x+3y+1
d) 345x2
If 2x – 3y = 1, then express 4x2−2x+3 in terms of y.
If y=2x+12x−1, we can express x in terms of y asx=a(y+1y−1).Find1a
