Answer:
Method 1 is distribution of the -1/2 to 5x and -9. Method 2 is simplification by multiplying -1/2 to both sides of the equation.
Step-by-step explanation:
Method 1: Method 2:
[tex]-\frac{1}{2} (5x-9)=17[/tex] [tex]-\frac{1}{2} (5x-9)=17[/tex]
[tex]-\frac{1}{2}[/tex](5x-9)=17 [tex]-\frac{1}{2}[/tex](5x-9)=17
[tex]-\frac{1}{2}[/tex]*5x-([tex]-\frac{1}{2}[/tex]*9)=17 [tex]-\frac{1}{2}[/tex]*(-2)(5x-9)=17*(-2)
[tex]-\frac{5}{2}[/tex]x+([tex]\frac{1}{2}[/tex]*9)=17 5x-9=-34
[tex]-\frac{5}{2}[/tex]x+9/2=17 5x-9+9=-34+9
([tex]-\frac{5}{2}[/tex]x+9/2=17)*2 5x=-25
-5x+9=34 5x/5=-25/5
-5x+9-9=34-9 x=-5
-5x=25
-5x/(-5)=25/(-5)
x=-5
