Question

Tìm x

12 + x + (-5)= -18

 

Answer 1

\(12+x+\left(-5\right)=-18\)

\(\Leftrightarrow x=-18-12+5\)

\(\Leftrightarrow x=-25\)

Answer 2

12 + x + ( -5 ) = -18

              7 + x = -18

                    x = -18 - 7

                    x = -25

 

Answer 3

12+x=-18+5=-13

x=-13+(-12)

x=-25

Answer 4

= (-18) - (-5) 

= -13

=(-13) - 12 

= -25 

X= -25 

Answer 5

x=-25

Answer 6

12 + x + [-5 ] = -18

              7 + x = -18

                    x = -18 - 7

                    x = -25
