Question

-7 + 2x = -37- (-26)

Answer 1

\(-7+2x=-37-\left(-26\right)\)

\(\Leftrightarrow-7+2x=-37+26\)

\(\Leftrightarrow2x=-37+26+7\)

\(\Leftrightarrow2x=-4\)

\(\Leftrightarrow x=-2\)

Answer 2

\(-7+2x=-37-\left(-26\right)\)

\(-7+2x=-11\)

\(2x=-11-\left(-7\right)\)

\(2x=-4\)

\(\Leftrightarrow x=-2\)

Answer 3

- 7 + 2x = -37 - ( - 26 )

- 7 + 2x = -37 + 26

- 7 + 2x = - 11

         2x = - 11 - ( - 7 )

         2x = - 11 + 7

         2x = - 4

           x = - 4 : 2

           x = - 2

Answer 4

\(-7+2x=-37-\left(-26\right)\)

\(\Rightarrow2x=-37+26+7\)

\(\Rightarrow2x=-4\)

\(\Rightarrow x=-2\)
