Answer:6 = 6x -2
Step-by-step explanation: Solve for the first variable in one of the equations, then substitute the result into the other equation.
Given
There are four defenders on a soccer team
if this represents 20 percent of the players on the team
Find out the total number of players on the team.
To proof
As given in question
four defenders on a soccer team
this represents 20 percent of the players on the team
let the total number of players = x
First convert 20% in the decimal form
Than the equation becomes
0.20x =4
now solving the above equation
we get
x = 20
thus the total number of players on the team are 20.
Hence proved

Answer: x = 12</h3>
=====================================================
Explanation:
C is the midpoint of AB. This means AC is half as long as AB
Put another way, AB is twice as long as AC
AB = 2*AC
AB = 2*( AC )
32 = 2*( x/2 + 10 ) .... substitution
32 = 2*(x/2) + 2*10 ... distribute
32 = x + 20
x+20 = 32
x = 32-20 .... subtract 20 from both sides
x = 12
---------
If x = 12, then
AC = x/2 + 10
AC = 12/2 + 10
AC = 6+10
AC = 16
which is half of AB = 32, so it confirms our answer.
Start by isolating y
(3x+1)/4=(5-2y)/6
(3x+1)6/4 =5-2y
(3x+1)3/2=5-2y
(9x+3)/2=5-2y
(9x+3)/2-5=-2y
(9x+3-10)/2=-2y
(9x-7)/-4=y
Hope I helped :)
