Answer:

x = 2.8

Step-by-step explanation:

[tex]7\left(-2x+4\right)=-4x[/tex]

[tex]-14x+28=-4x[/tex]

[tex]\mathrm{Subtract\:}28\mathrm{\:from\:both\:sides}[/tex]

[tex]-14x+28-28=-4x-28[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]-14x=-4x-28[/tex]

[tex]\mathrm{Add\:}4x\mathrm{\:to\:both\:sides}[/tex]

[tex]-14x+4x=-4x-28+4x[/tex]

[tex]\mathrm{Simplify}[/tex]

[tex]-10x=-28[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}-10[/tex]

[tex]\frac{-10x}{-10}=\frac{-28}{-10}[/tex]

[tex]x=\frac{14}{5}[/tex]

[tex]x=2.8[/tex]
