which of the following is the missing reason? Statements Reasons three halves times x plus 5 equals negative 4 Given 3x + 10 = −
den301095 [7]

Answer:

The missing reason is Subtraction Property of Equality.

Step-by-step explanation:

\frac{3}{2}x+5=-4    ⇒ (Given)

On Solving we get;

Multiplying 2 on both side we get;

2(\frac{3}{2}x+5)=-4\times2\\\\2\times \frac{3}{2}x+5\times 2=-4\times 2

3x+10=-8   ⇒ (Multiplication Property of Equality)

Now Subtracting Both side by 10 we get;

3x+10-10=-8-10

3x = -18     ⇒ (Subtraction Property of Equality)

Now Dividing both side by 3 we get;

\frac{3x}{3} = \frac{-18}{3}

x=-6        ⇒ (Division Property of Equality)

Hence the missing reason is Subtraction Property of Equality.
