Answer:
x= -4
Step-by-step explanation:
−2(4x+4)−3x−2=34
(−2)(4x)+(−2)(4)+−3x+−2=34(Distribute)
−8x+−8+−3x+−2=34
(−8x+−3x)+(−8+−2)=34(Combine Like Terms)
−11x+−10=34
−11x−10=34
−11x−10+10=34+10
−11x=44
−11x
/−11 = 44
/−11
x=−4
Get a common denominator which you can get by mutiplying by k-1
Now foil and distribute
Now combine the fractions and like terms
Now factor out a k+1
you can cancel out the k+1 leaving
