1.8x+2.8=2.5x+2.1

is it no soultion

I got 1 so I would say its one solution  

Step-by-step explanation:

1.8x+2.8=2.5x+2.1

Now move the 2.8 and 2.5x so..

1.8x - 2.5x=2.1 - 2.8 also switch the operation from addition to subtraciton.

Now subtract 1.8x to 2.5x which is -0.7x

Your new equation should look like this---> -0.7x=2.1 - 2.8

Now subtract 2.1 to 2.8

which is -0.7

So now your equcation should look like this--> -0.7 = -0.7

Now multiply both the -0.7 to 10 so

-0.7 · 10= -7

Now your equation is -7x = -7 now divide both sides by -7

which is 1

so x=1 which is only one solution so
