=>x+2=-9

=>x=-11

Answer 2

\(=>\left(x+2\right).28=7.\left(-36\right)\\ =>\left(x+2\right).28=-252\\ =>x+2=-252:28\\ =>x+2=-9\\ =>x=-11\)

Answer 3

\(\Rightarrow28.\left(x+2\right)=-36.7\)

\(\Rightarrow28x+56+252=0\)

\(\Rightarrow28x=-308\)

\(\Rightarrow x=-11\)

Answer 4

=>(x+2).28=7.(−36)=>(x+2).28=−252=>x+2=−252:28=>x+2=−9=>x=−11

Answer 5

x=(-9)
