Give a backward-chaining proof of the sentence 7 ≤ 3 + 9. (be sure, of course, to use only the axioms given here, not anything else you may know about arithmetic.) show only the steps that leads to success, not the irrelevant steps.

b. give a forward-chaining proof of the sentence 7 ≤ 3 + 9. again, show only the steps that lead to success.

step-by-step explanation:

300pi

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
