Answer:

-4.5

Step-by-step explanation:

15(2-x)=13(3-x)

Expand parentheses:

30-15x=39-13x

Add 15x to both sides:

30=2x+39

Subtract 39 from both sides:

2x=-9

Divide both sides by 2:

x=-4.5

Hope this helps!

Answer:

[tex]x = - 4.5 \\ [/tex]

Step-by-step explanation:

[tex]15(2 - x) = 13(3 - x) \\ 30 - 15x = 39 - 13x \\ - 15x + 13x = - 30 + 39 \\ - 2x = 9 \\ \frac{ - 2x}{ - 2} = \frac{9}{ - 2} \\ x = - 4.5[/tex]

hope this helps

brainliest appreciated

good luck! have a nice day!
