How would I start to solve number 15? Would I use distributive property?

-5-x=2x-(4x+6)

Using the distributive property is the correct first step. (4x+6) is being multiplied by -1, so distributing gives

-5-x=2x+(-4x-6)
-5-x=2x+((-4x)+(-6))

Now, using the associative property of addition, you get

-5-x=(2x+(-4x))+(-6)
-5-x=(2x-4x)-6

Simplify the right hand side:

-5-x=-2x-6

Add 5 and 2x to both sides.

(2x+5)-5-x=(2x+5)-2x-6

On the left side, use the associative property. On the right, commutativity and associativity:

2x+(5-5)-x=5+(2x-2x)-6

Simplify.

2x-x=-1
x=-1

1. Suppose a and b are real numbers where a > 0 and b < 0.
Nat2105 [25]

a) –a + b is negative

b) a – b is positive

c) b-a is negative

Step-by-step explanation:

1. Suppose a and b are real numbers where a > 0 and b < 0.

a. Is –a + b positive or negative. Explain how you know.

We know a > 0 and b < 0. so, let a =6 and b = -5

Putting values:

–a + b

= -(6)+(-5) = -6-5 = -11

So, –a + b is negative

b. Is a – b positive or negative? Explain how you know.

We know a > 0 and b < 0. so, let a =6 and b = -5

Putting values:

a - b

=6-(-5) = 6+5 = 11

So, a – b is positive

c. Is b – a positive or negative. Explain how you know

We know a > 0 and b < 0. so, let a =6 and b = -5

Putting values:

b-a

=(-5)-(6)

= -5-6

= -11

So, b-a is negative
