Three times a number increased by 8 is no more than the number decreased by 4. Find the number ( please write and solve inequali
ty!!)
1 answer:
Three times a number = 3x
Increased by 8 = + 8
So far we have: 3x + 8
no more than = <=
the number decreased by 4 = x -4
Put it all together and we have:
3x + 8 <= x - 4
Solve for x
3x + 8 <= x - 4
3x - x <= -4 - 8
2x <= -12
2x / 2 <= -12 / 2
x <= -6
-6 is the number / answer.
