ok so for number one (i will explain them)
\[5x +2 = 4x -9\]
\[9x +2 =-9\]
then you minus two from both sides and they you will come out with
\[9x= -7\]

yes ok so you get the answer for number one is to
group like terms take the x over the equal sign then change the signe before it so positive 4x becomes - ...5x-4x=x the two u carried over becomes negatie -9-2=-11 ur welcome try some using this principle
x=-11
