11 less than three times a number is the same as 75 less than the product of -1 and the number. Find the value of the number.

Let's translate the two expressions into formulae:

11 less than three times a number:

75 less than the product of -1 and the number

Those two are the same, so we have

Add to both sides:

Add 11 to both sides:

Divide both sides by 4 to get the final answer.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
