Solve : `3a+5b=-9`, `2a+5b=-11`.

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

Solve (2b)/3-5=3

Solve for a and b when 2a+3b=(17)/(5),5a+b=2

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

Solve :- (-11) xx (-9) xx (-5) xx (-6) xx (-3) = ?

Factorise: 9a (3a-5b) - 12 a ^(2) (3a - 5b )

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

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

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)=?
