Answer:
[tex]x=-4[/tex]
Step-by-step explanation:
[tex]9-4(2x-1)=45[/tex]
First, we expand the equation using the distributive rule:
[tex]x(y-z)=xy-xz[/tex]
Hence, [tex]9-4*2x-4*-1=45[/tex]
Simplify: [tex]9-8x+4=45[/tex]
Add like terms:
[tex]13-8x=45[/tex]
Subtract 13 from both sides: [tex]-8x=32[/tex]
Divide both sides by -8:
[tex]x=-4[/tex]
