Question

The first and second steps to solve the equation 3x/5+5=20 are shown below.

3x/5+5=20-5

3x/5(5/3)=15(5/3)


Which property was applied in the second step?

Answer 1

Answer: C

Explanation:

Answer 2

`\large{\boxed{\text{the multiplication property of equality}}}`

Explanation:

`(3x)/(5)+5=20\qquad\text{subtract 5 from both sides}\\\boxed{\text{the subtraction property of equality}}\\\\(3x)/(5)+5-5=20-5\\\\(3x)/(5)=15\qquad\text{multiply both sides by}\ (5)/(3)\\\boxed{\text{the multiplication property of equality}}\\\\(3\!\!\!\!\diagup^1)/(5\!\!\!\!\diagup_1)\cdot(5\!\!\!\!\diagup^1x)/(3\!\!\!\!\diagup_1)=(5)/(3\!\!\!\!\diagup_1)\cdot15\!\!\!\!\!\diagup^5\\\\x=(5)(5)\\\\x=25`
