Answer:
[tex]x = \frac{50}{3} \\ [/tex]
Step-by-step explanation:
[tex]1.2x+5=0.9x+10 \\ 1.2x - 0.9x = 10 - 5 \\ 0.3x = 5 \\ \\ x = \frac{5}{0.3} \\ \\ x = \frac{5 \times 10}{3} \\ \\ x = \frac{50}{3} [/tex]
Answer:
x = 16.2/3
Step-by-step explanation:
So to start off we need to make the two x's one.
So using the equation 1.2x + 5 = .9x + 10
We subtract .9x from 1.2x.
And we get .3x + 5 = 10.
Now we need to make the 5 and 10 one.
So now we subtract 5 from 10.
So now the equation looks like this .3x = 5.
So now we just divide 5 by .3x to get x by itself.
Hence, x is 16.2/3.
