Sagot :
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]
