1.5r+15=2.25r
Combine like terms: 1.5r+15-1.5r=2.25r-1.5r
15=0.75r
Get the unknown alone: 15/.75=.75/.75r
20=r or r=20 :)

Answer:
<u>The width of the top surface of the desk is 1.4 feet.</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Length of the top surface of a desk = 5.6 feet
Width of the top surface of a desk= x
2. Let's find the width of the top surface of the desk
Length of the top surface of a desk = Four times the width
5.6 = 4x
5.6/4 = 4x/4 (Dividing by 4 at both sides)
1.4 = x
<u>The width of the top surface of the desk is 1.4 feet.</u>
Answer:
Step-by-step explanation:
Given the equation as

apply multiplication property of equality where you multiply every term by 5

3x-15=60------------------apply addition property of equality
3x-15+15=60+15
3x=75--------------------------appy division property of equality by dividing both sides by 3
3x/3=75/3
x=25
