Hello there!
Thanks for posting your question!
Answer: x=18 and 18=x. *The answer must have negative sign.*
Explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
First, subtract by 3 both sides of an equation.
2x+3-3=39-3
Then, simplify by equation.
2x=36
Next, divide by 2 both sides of an equation.
2x/2=36/2
Finally, simplify by equation and it just gives us the final answer.
36/2=18
18*2=36
2*18=36
36/18=2
x=18 and 18=x
Hope this helps!
Thanks!
Have a great day!
