Question

2.5w - 5 < 2w + 5 ??????????????

Answer 1

w < 20

Explanation:

2.5w - 5 < 2w + 5

let's move the -5 to the right side of the equation by adding +5 to both sides

2.5w - 5 + 5< 2w + 5 + 5

2.5w < 2w + 10

Now move the 2w from the right side to the left side by subtracting 2w from both sides

2.5w - 2w < 2w - 2w +10

0.5w < 10

So now we need to isolate the w by dividing both sides by 0.5

0.5w / 0.5 < 10/0.5

w < 20
