3x-5y-4=0 and 9x=2y+7, solve for x and y

Solve:- 3x-5y-4=0, 9x=2y+7

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

3x+5y=9 and 4x+3y=7 then find x+y

If 8x + 5y = 9, 3x + 2y = 4, then the value of x and y are

Solve : (3x + 2y - 7)^(2) + (5x + 7y - 13)^(2) = 0 , for real values of x and y.

Show that the lines 2x + 3y - 8 = 0 , x - 5y + 9 = 0 and 3x + 4y - 11 = 0 are concurrent.

Two sides of a triangle are 2x -y =0 and x + y = 3. If its centroid is (2, 3) its third side is (A) x + 5y – 9 = 0 (B) 5x – Y – 9 = 0 (C) x + 5y + 9 = 0 D) 5x – y + 9 = 0

solve for x and y - 2x+3y=7 3x-4y=2

Prove that the straight lines 4x+7y=9, 5x-8y+15=0 and 9x-y+6=0 are concurrent.
