Explanation

To solve for  x in the equation  3889+12.950−x=47.97, follow these steps:

1: Combine the constants on the left side

3889+12.950=3901.950

So the equation becomes:

3901.950−x=47.97

2: Isolate x by subtracting 3901.950 from both sides:

−x=47.97−3901.950

Perform the subtraction on the right side:

47.97−3901.950=−3853.98

Thus:

 −x=−3853.98

3: Solve forx by multiplying both sides by -1:

x=3853.98
