Question

3х - 2 = 7

so my teacher is telling me to solve this but idk how to and my block exam is coming up so i need to know how to do these ​

Answer 1

x=3

Explanation:

The x variable would equal 3 because 3x3=9. Then 9-2=7.

Answer 2

x = 3

Explanation:

3x - 2 = 7

Add two to both sides because it's a negative

3x = 9

Divide by three by both sides to get the x by itself

9/3=3

x = 3

good luck on your exam!
