R + d = 1750
r = d + 450

d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays

r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100

<h2>Answer: x = 6</h2>

* = things that have changed or are being changed

<h2>Explanation:</h2>

1. rearrange terms

*4 4 + 3 * = 5 + 2 + 2 0

*3x + 44* = 5x + 2 + 20

2. combine like terms

3 + 44 = *5x + 2* + 20

3 + 44 = *7x* + 20

3. Subtract 4 4 from both sides of the equation

3x + 44 = 7x + 20

3x + 44 *-44* = 7x + 20 *-44*

4. Simplify

(Subtract the numbers)

3x + *44 - 44* = 7x + 20 - 44

3x = 7x + 20 - 44

(Again)

3x = 7x + 20 *- 44*

3x = 7x - 24

5. Subtract 7 from both sides of the equation

3x = 7x - 24

3x *- 7x* = 7x - 24 *- 7x*

6. Combine like terms

*3x - 7x* = 7x - 24 - 7x

*-4x* = 7x - 24 - 7x

(Again)

-4x = *7x* - 24 *- 7x*

-4x = - 24

7. Divide both sides of the equation by the same term

-4x = - 24

$\frac{-4x}{*-4*} = \frac{-24}{*-4*}$

8. Simplify

(Cancel terms that are in both the numerator and denominator)

$* \frac{-4x}{-4} * = \frac{-24}{-4}$

*x* = $\frac{-24}{-4}$

(Divide the numbers)

x = $\frac{-24}{-4}$

x = 6
