Answer:

x=-2

Step-by-step explanation:

9.75+4.99x=9.99x+19.75

Simply Both Sides(change the order of 9.75 and 4.99x in this case)

4.99x+9.75=9.99x+19.75

Subtract 9.99x from both sides

4.99x+9.75−9.99x=9.99x+19.75−9.99x

−5x+9.75=19.75

Subtract 9.75 from both sides now

−5x+9.75−9.75=19.75−9.75

−5x=10

Divide both sides by -5 and boom

−5x/-5=10/-5

x=−2
