X=-9. To do this equation you had to do a multi-step problem solver teqnique. But I would recommend Khan Academy for any questions. My best advice would be for that. Or you can just try to simplify the equation down as much as possible. To do so, you'd have to multiply the first parentheses by -3. Which would equal: (-9x+-65) -(10+x) =35. Next you will add 65 to each side. But always remember if you to something on this side, you must always do it on the other side over the equal sign. Which would equal to: -9-(10+x) =100. So from here you will subract 10 to eliminate the number 10. Like so: -9x+x=90. So from here, you will just add the two x's together because, in math simplifying in the most important thing ever!: -10x/10=90/10. (The parentheses mean division btw) Then after dividing you will get x=-9. Hope that helps and after getting this through your head it's a piece of cake. Good luck

Answer:
Step-by-step explanation:
Phil is going to store to buy a hat and a coat.
Let $x represent the cost of the cos of the hat. The coat cost 3 times as much as the hat. It means that the cost of the coat will be 3×x = $3x
His mom tells him that he cannot spend more than $120. Assuming he spends exactly $120. It means that
3x + x = 120
4x = 120
x = 120/ 4 = 30
The hat costs $30
The coat costs 30×3 = $90
The most he can spend on a coat is $90 since he cannot spend more than $120
Answer:
x=10
Step-by-step explanation:
write equation like this:
14x-77=9x-27
use order of operations aka PEMDAS to solve
youre answer would be x=10
