is there a solution for x + 5.1 <= -2.4 Dec 26 | L from Jacksonville, NC | 2 Answers | 0 Votes Mark favorite Subscribe Comment
x + 5.1 <=-2.4 Subtract 5.1 from both sides: x <= -2.4 - 5.1 x <= -7.5 Dec 26 | Kevin F. Comment Comments if i use a number less than -7.5 for x then would this be a false solution? i.e. try -5 for x. -5 + 5.1 <= -2.4 1. <=-2.4 cannot be true Dec 26 | L from Jacksonville, NC Correct. The solution is all values of x that are less than or equal to -7.5. The statement would be false for all values of x that are greater than -7.5, such as -5. Dec 26 | Kevin F. Comment

x+5.1≤-2.4 therefore subtracting both sides of the inequality by 5.1 we have x+5.1-5.1≤-2.4-5.1 ⇒ x≤-7.5 Dec 26 | Jean-Sebastien R. Comment
