Solve for 'u' and 'V:

Linear Equations in two variables

DATE OF SUB.: 06/06/2

2. Solve for 'x' and 'y :

3(2u + v) = 7uv ; 3( u + 3V ) = 110v

ASSIGN. NO.: 1

3. Solve for 'x' and 'y : 23x - 29y = 98

2(x+2y) 3(3x-2y)

61

4(x+2y) 5(3x-2y) - 50

4) Solve for 'X' and 'y :-

; 29% - 23y = 110

(x+y) - (x-y)+3; 26

5 Solve for 'x' and 'y : 3x - 9++ 2 = 10

2(x+y) - 36-v , where x+y+0 and X-y +0.

;

6 Solve for 'x' and 'Y' :

2y + 5+11 = 10

+ y = 0.8 ;

Solve for 'X' and 'y': 7(y+3) – 2(x+2) = 14 ; 4(y-2) + 3(x-3) =2 ,( Use Cross Multiplication Me

= 10 , by using Substitution Method.

8. Solve for 'x and V: 0.4x + 0.3y = 1.7 ; 0.7x -0.2y = 0.8

9. Solve for 'X' and 'v : + = 3 ; + = 21 , where xư0, y=0.

10. Solve for 'X' and 'y':

8 ;x*0; y#0, by using Elimination M

11, solve for 'x' and 'V: + = + = 0, hence find 'a' for which y=

12. Solve for x and y: + 302 = 499 : 103 + = 501

13. If 2x + y =35 and 3x + 3y =65 is a pair of linear equations, then find the value of

14. Solve for 'x' and 'v:

= -1 ; + 5 = 10

15) Solve for 'x' and 'v : 6x + 3y = 8x + 9y - 5 = 10x + 12y-8

(16) Solve for 'x' and 'y' : a( x + y )+ b[x - y)=a? - ab + b2 ; a(x + y) - b(x - y) = a2 + ab-

by using Elimination Method.

12 Solve for x' and 'y' : ax + by = 1 ; bx + ay = 42-1, by using Elimination
