`(x)/(2)+(2y)/(3)=-1` And `x-(y)/(3)`

Solve for x and y : (x)/(2)+(2y)/(3)=-1 x-(y)/(3)=3

Solve the following equations by Cramer’s method. 3x - 2y = (5)/(2), (1)/(3)x + 3y = - (4)/(3)

Solve the following pair of linear equations by the elimination method and the substitution method: (i) x+y=5" "a n d" "2x 3y=4 (ii) 2x+4y=10" "a n d" "2x 2y=2 (iii) 3x 5y 4=0" "a n d" "9x=2y+7 (iv) x/2+(2y)/3=-1 and x-y/3=3

(3) 3x-2y=(5)/(2) (1)/(3)x+3y=-(4)/(3)

Find the following products and verify the result for x=-1,y=-2:(3x-5y)(x+y)(2)(x^(2)y-1)(3-2x^(2)y)((1)/(3)x-(y^(2))/(5))((1)/(3)x+(y^(2))/(5))

3x-2y=(5)/(2),(1)/(3)x+3y=(-4)/(3)

(5)/(8)x+(7)/(2)y=(3)/(2) (1)/(6)x-(2)/(3)y=1 If the ordered pair (x, y) satisfies the system of equations above, what is the sum of the values of x and y?
