Answer:
Combine like terms
Addition property of equality
Division property of equality
Step-by-step explanation:
13x+5x=18x
18x-4=5 negative 4 would become positive and you will as it to 5 to get 9
18x=9 simply divide
The reasons required to complete this question are;
This is an equation in which we just need to write the accurate steps on each required side.
We are asked to prove x = 1/2 from 5x - 4 + 13x = 5
On the statement side, we are given an equation
[tex]5x -4 + 13x = 5[/tex]
On the reason side, we already have our answer as Given
On the statement side, we have an equation
[tex]18x-4=5[/tex]
On the reason side, we should write down addition property of equality
we have an equation
[tex]18x = 9[/tex]
On the reason side, we should write Combine like terms
On the statement side, we have an equation
[tex]x = \frac{1}{2}[/tex]
On the reason side, we should write down Division property of equality.
Within the four steps above, we were able to justify and prove how x = 1/2.
