Find the correct choice. {:("(A)"5x+2y=16),(" "7x-4y=2):}}" (P)no solution" {:("(B)"5x+2y=16),(" "3x+(6)/(5)y=2):}}" (Q) unique solution" {:("(C)"5x+2y=16),(" "(15)/(2)x+3y=24):}}" (R) infinite number of solution"

Solve, 7x+3<5x+9, x in R . express the solution on a number line.

The linear equation 7x+9y=8 has a unique solutions

(i) Is x=5 a solution of the equation x^(2)-2x-15=0 ? (ii) Is x=-3 a solution of the equation 2x^(2)-7x+9=0 ?

Solve : (7x +3)/(4) + (9x -5)/(8) = (16x-3)/(16) The following steps are involved in solving the above problem. Arrange them in sequential order (A) x = (-5)/(30) = (-1)/(6) (B) (7x + 3)/(4) + (9x -5)/(8) = (16x-3)/(16) rArr (14x + 6 + 9x -5)/(8) = (16x -3)/(16) (C) (23x + 1)/(8) = (16x -3)/(16) rArr 23x + 1 = (16x -3)/(2) (D) 46x + 2 = 16x - 3 rArr 30 x = -5

Solve: 7x+3<5x+9 represent the solution on the real line.
