Question

Se considera ecuatia x+1 supra 4 =ax+a -1 supra 3:Rezolvati ecatia pentru a=2

Answer 1

(x+1)/4=ax+a-1
(x+1)/4=2x+2-1
(x+1)/4=2x+1
x+1=4(2x+1)
x+1=8x+4
8x-x=1-4
7x=-3
x=-3/7

Answer 2

(x+1)supar 4=ax+a-1

(x+1)supar4=2x+2-1

(x+1)supara4=2x+1

x+1=4(2x+1)

x+1=8x+4

8x-x=1-4

7x=-3

x=-3/7..............................
