you are going to follow PEMDAS 1. can't do anything within the parhentisis so move past exponents to multiplication 2. the negative sign on the left can be multiplied inside the parhentisis making the problem simplify to -7+4x=9  3. you can now balance out the sides so subtract 4x to both sides and subtract 9 to both sides 4. it is now -16=.-4x  5. your goal is always to isolate the variable so in this case it is x  6. divide -4 on each side to get the x by itself  7. you should get x=4
