What is the intersection point of 2x+19y=3 and 1x-3=7y

Answers

$2x+19y=3\n19y=-2x+3\ny=-(2)/(19)x+(3)/(19)\n\nx-3=7y\ny=(1)/(7)x-(3)/(7)\n\n-(2)/(19)x+(3)/(19)=(1)/(7)x-(3)/(7)\n-(14)/(133)x+(21)/(133)=(19)/(133)x-(57)/(133)\n(78)/(133)=(33)/(133)x\n(78)/(33)=x\nx=(26)/(11)\n\n((26)/(11))-3=7y\n((26)/(11))-(33)/(11)=7y\n(-7)/(11)=7y\n-11=y$

(26/11, -11)

2x + 19y = 3 ⇒ 2x + 19y = 3 ⇒ 2x + 19y = 3
1x - 3 = 7y    ⇒ 1x -   7y = 3 ⇒ 2x + 14y = 6
      5y = -3
   5     5
   y = -3/5
      2x + 19(-3/5) = 3
   2x - 11 2/5 = 3
      +11 2/5 +11 2/5
   2x = 14 2/5

factor n^2-10n+24

Answers

factors of 24 that would also add up to -10 would be -12 and 2 soo. you would factor out the n's to get:
(n-12)(n+2)

Your question is : -

n² - 10n +24

we split -10 n into two numbers such that product is 24 and sum is -10n. We find the numbers be -6 and -4.

n² - 6n - 4n + 24

= n(n-6) - 4(n-6)

= (n-4)(n-6)
