Question

-3x - 5 = 10

so im a stuck on these kind of questions and i really dont get them and my block exam is coming up ​

Answer 1

Hey :)

Good luck in your exams!

x = -5

Add 5 to both sides
−3x = 10+5


Add 10 and 5 to get 15
−3x = 15

Divide both sides by −3
x= 15/-3
​

Divide 15 by −3 to get −5
x = -5


Hope this helps :)

Answer 2

X=5

Explanation:

-3x-5=10

+5 +5

-3x=10

divide both sides by 3 and you get x=5
