Question

tìm x: x + x + x + 91 = -2

Answer 1

x+x+x+91=-2

x.3+91    = -2

        x.3   = -2-91

        x.3   =-93

         x     = -93:3 

         x     = -31

vậy x=-31

Answer 2

#)Trả lời :

x + x + x + 91 = -2

Answer 3

\(x+x+x+91=-2\)

\(\Leftrightarrow x.3+91=-2\)

\(\Leftrightarrow x.3=-2-91\)

\(\Leftrightarrow x.3=-93\)

\(\Leftrightarrow x=-93:3\)

\(\Leftrightarrow x=-31\)

Answer 4

\(x+x+x+91=-2\)

\(\Rightarrow3x+91=-2\)

\(\Rightarrow3x=-2-91\)

\(\Rightarrow3x=-93\)

\(\Rightarrow x=-\frac{93}{3}\)

\(\Rightarrow x=-31\)

Answer 5

x + x + x + 91 = -2

\(\Rightarrow\) 3x + 91 = -2

                    3x = (-2) - 91

                    3x = -93

                        x = -93 : 3 = -31

Answer 6

\(x+x+x+91=-2\)

\(\Rightarrow3x+91=-2\)

\(\Rightarrow3x=-2-91\)

\(\Rightarrow3x=-93\)

\(\Rightarrow x=-31\)

Vậy x = -31

Answer 7

 x + x + x + 91 = -2

3x = -2-91=-93

x= -93:3=-31

Answer 8

x + x + x +91 = - 2

3x + 91 = - 2

3x = - 2 - 91

3x = - 93

x = - 93 : 3

x = - 31.
