Answer:

x=-5.25

Step-by-step explanation:

Original equation:

2(3-x)-1.4(5-2x)=2x+5.3

Distribute:

6-2x-7+2.8x=2x+5.3

Group like terms:

(6-7)+(2.8x-2x)=2x+5.3

Add like terms:

-1+0.8x=2x+5.3

Add 1 to both sides

0.8x=2x+6.3

Subtract 2x from both sides

-1.2x=6.3

Divide both sides by -1.2

x=-5.25
