[" (2) "(2)/(x)+(3)/(5)=22],[(5)/(x)-(4)/(y)=9]

Converted combinations of the following equations into the pair of linear equations Solve the problem (2)/(x)+(3)/(y)=22,(5)/(x)-(4)/(y)=9

Solve for x,y(5)/(x)+(3)/(y)=30 and (9)/(x)-(5)/(y)=2

Find each of the following products: (i) (x - 4)(x - 4) (ii) (2x - 3y)(2x - 3y) (iii) ((3)/(4) x - (5)/(6) y) ((3)/(4)x - (5)/(6) y) (iv) (x - (3)/(x)) (x - (3)/(x)) (v) ((1)/(3) x^(2) - 9) ((1)/(3) x^(2) - 9) (vi) ((1)/(2) y^(2) - (1)/(3) y) ((1)/(2) y^(2) - (1)/(3) y)

Find each of the following products: (i) (x + 6) (x + 6) (ii) (4x + 5y) (4x + 5y) (iii) (7a + 9b) (7a + 9b) (iv) ((2)/(3) x + (4)/(5)y) ((2)/(3) x + (4)/(5) y) (v) (x^(2) + 7)(x^(2) + 7) (vi) ((5)/(6) a^(2) + 2) ((5)/(6) a^(2) + 2)

Add the following (8)/(5)x+(11)/(7)y+(9)/(4)xy,-(3)/(2)x-(5)/(3)y-(9)/(5)xy

If (x)/(y)=(1)/(3), then (x^(2)+y^(2))/(x^(2)-y^(2))=?(a)-(10)/(9) (b) (5)/(4)(c)-(5)/(4)(d)-(5)/(3)

Simplify :((-3)/(2)x(4)/(5))+((9)/(5)x(-10)/(3))-((1)/(2)x(3)/(4))

simplify :(3)/(11)x(-5)/(6)x(-(22)/(9))x(-(9)/(5))

Evaluate: [(x^(5y-5)xx x^(5-2y))/(x^(4y-6)xx x^(2y-9))]^(-(4)/(3))
