Question

EXERCISE - 6,2
iii) 2x - y=7
1. Find three different solutions of the each of the following equations.
i) 3x + 4y = 7
ii) y=6x
iv) 13x - 12y = 25 v) 10x + 1ly = 21
vi) x+y=0​

Answer 1

Answer:

13k

> 13k = 2 2 : k= 13 y 4- 2x y = 4- 2(0) = = y= 4- 2(2) = y = 4- 2(1) 3 y=4-2(3) : 0. EXERCISE-6.2 2 1. Find three different solutions of the each of the following equations. i) 3x + 4y= 7 i11) 2x - y=7 ii) y=6x vi) x+y=0 We see fore here is one value iv) 13x v) 10x + 1ly=21 12y 25 2. If (0, a) and (b, 0) are the solutions of the following linear equations. Find i) 8x y 34 he value of 'x'a i11) 5x - 2y+3 nd take the vak -axis. Let us p 2, 0), (1, 2) raph. If we j- .2oints we obt ii) 3x= 7y- 21 - 5y D10 3. Check which of the following is solution of the equation 2x iv) (2/3,-V3) i) (0, 2) ii) (0,-2) iii) (5, 0) Do all 4. Find the value of k, ifx=2, y=1 is a solution of the equation 2x+333DK. Fine on the lir solutions of the resultant equation. Now e line sa:
