Answer:

x=-5.25

Step-by-step explanation:

Original equation:

[tex]2(3-x)-1.4(5-2x)=2x+5.3[/tex]

Distribute:

[tex]6-2x-7+2.8x=2x+5.3[/tex]

Group like terms:

[tex](6-7)+(2.8x-2x)=2x+5.3[/tex]

Add like terms:

[tex]-1+0.8x=2x+5.3[/tex]

Add 1 to both sides

[tex]0.8x=2x+6.3[/tex]

Subtract 2x from both sides

[tex]-1.2x=6.3[/tex]

Divide both sides by -1.2

[tex]x=-5.25[/tex]
