Question

X + 4.5 ≤ 12 what is x

Answer 1

The answer to x is infinity

Explanation:

there is an infinite amount of numbers that when added to 4.5 are equal or less than 12 so the whole range of numbers for x can be written as (-infinity,7.5]

Answer 2

x<7.5

Explanation:

step 1 subtract 4.5 by both sides.

x+4.5−4.5<12−4.5

x<7.5
