5(2x - 8) + 15 = -15
               -15      -15     subtract 15 from each side
5(2x - 8) = -30
  ÷5             ÷5             divide both sides by 5
2x - 8 = -6
     +8    +8                   add 8 to each side
2x=2
÷2  ÷2                          divide both sides by 3
x = 1

Checking:
5(2(1)-8) + 15 = -15
5(-6) + 15 = -15
-30 + 15 = -15
-15 = -15             Correct! x=1

5(2x-8) + 15 = -15

Distribute the 5 into (2x-8) :
10x - 40 + 15 = -15

Add -25 and 15 :
10x - 25 = -15

Add 10 to both sides:
10x = -15 + 25
10x = 10

Divide both sides by 10 :
x = 10/10
x = 1

(MATH) What is the reason for each step in the solution of the inequality?
Rama09 [41]

Step-by-step explanation:

Inequalities are solved just like equations the only difference is that the inequality sign has to be considered.

We are writing the steps with reason

So,

1. Given

-38-3(x+5)>6x-17

2. Distributive property:

-38-3x-15>6x-17

3. Combine like terms

-3x-53>6x-17

4. Subtraction property of order

-3x-53-6x>-17

-9x-53> -17

5. Addition property of order

-9x> -17+53

-9x>36

6. Division property of order
