Hello there!
Answer: ⇒⇒⇒⇒⇒⇒ [tex]x=-\frac{7}{4}[/tex]
_______________________________________________________________
Step-by-step explanation:
First you had to add similar elements.
[tex]2x+5x=7x[/tex]
[tex]7x+8=10x+15+x[/tex]
Group like terms:
↓↓↓↓↓↓↓↓↓↓↓↓↓
[tex]7x+8=10x+x+15[/tex]
Then you add similar elements.
[tex]10x+x=11x[/tex]
[tex]7x+8=11x+15[/tex]
Subtract by 8 from both sides of equation.
[tex]7x+8-8=11x+15-8[/tex]
Simplify.
[tex]7x=11x+7[/tex]
Then you had to subtract by 11x from both sides of equation.
[tex]7x-11x=11x+7-11x[/tex]
Simplify.
[tex]-4x=7[/tex]
Divide by -4 from both sides of equation.
[tex]\frac{-4x}{-4}=\frac{7}{-4}[/tex]
Simplify it should be the correct answer.
[tex]x=-\frac{7}{4}[/tex]
