Question

315+3.(x+1)=251

 

Answer 1

=>3(x+1)=-64

=>x+1=-64/3

=>x=-67/3

Answer 2

315+3.(x+1)=251

<=>3.(x+1)=251-315

<=>3.(x+1)=-64

<=>x+1=-64:3

<=>x+1=\(-\dfrac{64}{3}\)

<=>x=\(-\dfrac{64}{3}-1\)

<=>x=-\(\dfrac{67}{3}\)

Answer 3

315 + 3 (x + 1) = 251

3 (x + 1) = 251 - 315

3 (x + 1) = - 64

x + 1 = - 64 : 3

x + 1 = \(\dfrac{-64}{3}\) 

x = \(\dfrac{-64}{3}-1\)

x = \(\dfrac{-67}{3}\)
