Find the values of x and y if: (x-1,y+3)=(4,4)

Find the value of x and y , if (x+5,2y-x+3)=(-3,4) .

Find the value of x , y 2x+3y=6 3x-2y=4 .

If x - (1)/(x) = y , x ne 0 , find the value of (x- (1)/ (x) - 2y ) ^(3)

Find (x+y)+(x-y), if x=5/4, y=(-1)/3 (ii) x=2/7, y=4/3 (iii) x=1/4, y=3/2

If 2x + y = 23 and 4x - y = 19 , then find the values of 5y - 2x and (y)/(x) - 2 .

Find the values o x and y if: (5x-3y,y-3x)=(4,-4)
