Resolver la siguiente ecuación por eliminación o sustitución: a-8b= -9 a-2b= -7
Crazy boy [7]

Answer: Solution: a=\dfrac{-19}{3} and b=\dfrac{1}{3} .

Step-by-step explanation:

The given pair of equations:

a-8b= -9\ ...(i)\\\\ a-2b= -7\ ...(ii)

Eliminate equation (i) from (ii) , we get

-2b-(-8b)=-7-(-9)\\\\\Rightarrow\ -2b+8b=-7+9\\\\\Rightarrow\ 6b=2\\\\\Rightarrow\ b=\dfrac{1}{3}

Put value of b in (ii) , we get

a-2\times\dfrac{1}{3}=-7\\\\\Rightarrow\ a=-7+\dfrac{2}{3}\\\\\Rightarrow\ a=\dfrac{-21+2}{3}\\\\\Rightarrow\ a=\dfrac{-19}{3}

Solution: a=\dfrac{-19}{3} and b=\dfrac{1}{3} .

Triss [41]

Answer:

x= 1/20

Step-by-step explanation:

-1/2x = -10

multiply by 2x on each side

2x(-1/2x) = -10*2x

-1 = -20x

divide by -20

-1/-20 = -20x/-20

1/20 =x
