Answer: [tex]x=\frac{24}{5}[/tex] , (decimal: x=4.8)
Step-by-step explanation:
[tex]7x-3\left(2x-9\right)=6x+3[/tex]
[tex]7x-6x+27=6x+3[/tex]
[tex]x+27=6x+3[/tex]
[tex]x+27-27=6x+3-27[/tex]
[tex]x=6x-24[/tex][tex]x-6x=6x-24-6x[/tex]
[tex]-5x=-24[/tex]
[tex]\frac{-5x}{-5}=\frac{-24}{-5}[/tex]
[tex]x=\frac{24}{5}[/tex]
Answer:
[tex]x=\frac{24}{5}[/tex]
Step-by-step explanation:
[tex]7x-3\left(2x-9\right)=6x+3[/tex]
Use the distributive property to multiply -3 by 2x-9:-
[tex]7x-6x+27=6x+3[/tex]
Combine 7x and -6x to get x:-
[tex]x+27=6x+3[/tex]
Subtract 6x from both sides:-
[tex]x+27-6x=3[/tex]
Combine x and -6x to get -5x:-
[tex]-5x+27=3[/tex]
Subtract 27 from both sides:-
[tex]-5x=3-27[/tex]
[tex]-5x=-24[/tex]
Divide both sides by -5:-
[tex]x=\frac{24}{5}[/tex]
