30+6.25x<12+9.75x

What is the answer to this?

First, move the variable to the left side like this. 6.25x - 9.75x + 30<12

Then you move the constant to the right side and change it sign

6.25x - 9.75x <12 - 30.

Collect the like terms

6.25x - 9.75x = - 3.5x

-3.5x <12 - 30.

Calculate the difference

12 - 30 = - 18

- 3.5x < - 18.

Divide both sides of the inequality by - 3.5 and flip the inequality sign and you'll get your answer by 36/7
