Question

How do you solve the equation 2x - 125 = 400

Answer 1

You add -125 by its opposite which is 125 so 2x(-125+125)=400+125
2x=525
You then divide both sides by 2 and you get
X=262.5

Answer 2

2x-125=400

Add 125 to both sides

2x-125+125=400+125

2x=525

Divide both sides by 2

2x/2=525/2

x= 262.5

Let me check if my work is good

2(262.5)-125=400

525-125=400

400=400

So yes , my answer is good and I hope its help !
