" i) Solve "3a+5b=-9;2a+5b=-11

Solve:- 8a+5b=9 3a+2b=4 .

Solve (2b)/3-5=3

Solve the following simultaneous equations. 3a + 5b = 26, a + 5b = 22

Simplify the following : (a + 2c) + (3a + 5b) (c - 2a - 9b)

Solve the following simultaneous equations. 3a+5b=26,a+5b=22 .

If (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5, then (3a + 5b) : (9a - 2b)=? यदि (10a^3 + 4b^3) : (11a^3 - 15b^3 =7:5 है, तो (3a + 5b) : (9a - 2b)=?

Find the value of a and b . (sqrt11 - sqrt7 ) / (sqrt 11 + sqrt 7) = a - b sqrt 77 (i) a = 9/2 , b = 1/2 (ii) a = 2/9, b = 2/3 (iii) a = 2/5, b = 1/2 (iv) a = 9/2, b =5/2

Solve the following equation : 5x + 9/2 = 11/2

Subtract : 2a - 5b + 2c - 9" from "3a - 4b - c + 6

Solve by matrix inversion method the equations in each of the following: 2a - 5b + 1 = 0, 5a - 7b = 3
