2.	4x+6y=6;3x+7y=2 solve this linear equation in two variables fast please
Answer» Hey there ! 4x + 6y = 6 multiplied by 3 gives, 12x + 18Y = 18 3x + 7Y =2 multiples by 4 gives, 12x + 28 y = 8 . Subtracting both EQUATIONS, 12x + 18y = 18 12x + 28y = 8 ============= -10y = 10 So, y = -1 . Now, 4x - 6 =6 , 4x = 12 , x = 3 . So, ( x, y) = ( 3 , -1 ) is the required solution.

18.	Can anyone help me to understand the substitute method in linear equations in two variables?
Answer» First take out the equation in term of only a single variable, then put this value in second equation. For example: Let suppose we take. 2x+ y= 5.... (1) 2x+ 3Y= 15 ...(2) Now, we have to FIND the value of x in (1) so, 2x+ y=5... [Given] => 2x=5-y => x=(5-y)/2 Now,PUTTING this value in 2. => 2(5-y)/2 +3y= 15 => 5-y+3y= 15 => 5+2y= 15 => 2y= 10 => y= 5 Now,put the value of y in 1 => 2x+ 5 = 5 => 2x= 0 => x=0 _____________ Hope you UNDERSTAND my method.. ✌✌

22.	Without actual division, prove that x^4+2x^3+2x-3 is exact;y divisible by x^2+2x+3.pls, give an elaborative answer I'm not able to do it.
Answer» Let f(x) = x4 + 2x3 -2x2 + 2x - 3 g(x) = x2 + 2x - 3 = x(x + 3) - 1(x + 3) = (x - 1) (x + 3) Now f(x) will be EXACTLY divisible by g(x) if it is exactly divisible by (x - 1) as well as (x + 3) i.e. if f(1) = 0 and f ( -3) = 0 Now f(1) = 14 + 2.13 -2.12 + 2.1 - 3 = 1 + 2 - 2 + 2 - 3 = 0 => (x - 1) is a factor of f(x) f ( -3) = (-3)4 + 2.(-3)3 -2.(-3)2 + 2.(-3) - 3 = 81 - 54 - 18 - 6 - 3 = 0 => (x + 3) is a factor of f(x). => (x - 1) (x + 3) divides f (x) exactly Therefore, x2 + 2x - 3 is a factor of f(x)
