Hello there! :)
Answer:
[tex]\boxed{X=-8}[/tex]
*THE ANSWER SHOULD BE HAVE A NEGATIVE SIGN ONLY AT THIS TIME!
Step-by-step explanation:
Add by the similar into elements.
7x+6x=13x
13x+4+9=9x+5+3x
Add by the numbers from left/right.
4+9=13
13x+13=9x+3x+5
Group like terms means to switch sides.
13x+13=9x+3x+5
Add numbers.
9x+3x=12x
13x+13=12x+5
Subtract by 13 from both sides of an equation.
13x+13-13=12x+5-13
Simplify equation.
13-5=8
13x=12x-8
Subtract by 12x from both sides of an equation.
13x-12=12x-8-12x
Simplify.
x=-8
Final answer is x=-8
Hope this helps you!
Have a nice day! :)
