This is a simply problem. Just divide both sides the coefficient of x. Which is -2.
And the answer will be x = -4
Answer:
Check explanation
Step-by-step explanation:
Here, we want to make a prove;
Mathematically , since D is the midpoint of CE
Then;
CE = CD + DE
Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE
I.e CD = DE
Hence, we can express CE as follows;
CE = DE + DE
CE = 2 DE
Divide both sides by 2
CE/2 = DE
Hence; DE = 1/2 CE
Answer:
7
Step-by-step explanation:
5( x - 3)/2 - 1 = 9
5/2(x-3)-1=9
5/2x-15/2-1=9
5x-15-2=18
5x-17=18
5x=35
x=7
It can sometimes be rational
