STEPS FOR SOLVING LINEAR EQUATION
3y=4x+1
Swap sides so that all variable terms are on the left hand side.
4x+1=3y
Subtract 1 from both sides.
4x=3y−1
Divide both sides by 4.
4
4x
 =  
4
3y−1
  
Dividing by 4 undoes the multiplication by 4.
x=  
4
3y−1
  
 
        
             
        
        
        
Whenever a number is beside a parenthesis without a sign it means multiplication. So you would use PEMDAS work in parenthesis then exponents, multiplication (from left to right) addition and subtraction (from left to right). so you would add 20+3 and get 23 then multiply that by -5 to get -115 as your answer.

Answer:
6(3x-1)
Step-by-step explanation:
They both have a common factor of 6
So divide 6 and take it out to give:
6(3x-1)
 
        
             
        
        
        
DE is parallel to BC since D is the midpoint of
AB and E is the midpoint of AC.
<span>
Thus, DE and BC have the same slope (0.5) and basing on the formula for
midpoint, the length of DE would be the equal half of BC and is equal to 1.6
units</span>
 
The slope and length of DE, if the slope and
length of BC are 0.5 and 3.2 units, respectively are 0.5 and 1.6
respectively.
