Question

Which property was used to write the equation in step 2? Step 1: 5 (x minus 7) = 55. Step 2: 5 x minus 35 = 55. Step 3: 5 x = 90. Step 4: x = 18.

Answer 1

Answer:

Distributive Property

Step-by-step explanation:

If we have an equation where we multiply something in parentheses by a certain term, then we can apply the distributive property to simplify it.

In this case: $5(x-7)=55$

We can multiply $x-7$ by 5 to simplify this equation - this is the distributive property.

$5x - 35 = 55$

So the property used to write the equation in Step 2 was the distributive property.
