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
