The answer would be 65 and 66
65+66 = 131

a + (a + 1) = 131
           - 1       -1
2a              = 130
/2                   /2
a = 65
a + 1= 66

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} .
