Answer:
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
