Question

Use inverse operations to solve each equation. Explain each step and identify the property used to reach step. 19 = h/3 - 8

Answer 1

Answer: h = 81

==================================================

Step-by-step explanation:

19 = h/3 - 8

19+8 = h/3 - 8+8 .... see note 1

27 = h/3

h/3 = 27

3*(h/3) = 3*27 .... see note 2

h = 81

----------

• note 1: We add 8 to both sides to undo the "minus 8". This is the addition property of equality. Addition is the inverse of subtraction.
• note 2: We use the multiplication property of equality. This is where we can multiply both sides by the same number and keep the equation the same (basically balancing both sides). Multiplication is the opposite of division.
