`x-2/3 y=8/3; (2x)/5-y=7/5`

2x+5y=8/3, 3x-2y=5/6

3x+2y=5 2x-3y=7

5x-3y=8,3x+y=2 .

2x+3y=8 4x-5y=-6

{:(2x - 4y = 3),(5x - ky = 7.5):}

{:(2x - 4y = 3),(5x - ky = 7.5):}

3x+2y=5 2x+3y=7

If 2x+3y=34 and (x+y)/(y)=(13)/(8), then find the value of 5y+7x

Find each of the following products: (i) (x + 3) (x - 3) (ii) (2x + 5)(2x - 5) (ii) (8 + x)(8 - x) (iv) (7x + 11y) (7x - 11y) (v) (5x^(2) + (3)/(4) y^(2)) (5x^(2) - (3)/(4) y^(2)) (vi) ((4x)/(5) - (5y)/(3)) ((4x)/(5) + (5y)/(3)) (vii) (x + (1)/(x)) (x - (1)/(x)) (viii) ((1)/(x) + (1)/(y)) ((1)/(x) - (1)/(y)) (ix) (2a + (3)/(b)) (2a - (3)/(b))

If 17x -5y=8 and 14 x -7y =-7, what is the value of 3x + 2y ?
