Mathematics
1 answer:
Snezhnost [94]3 years ago
8 0

Answer:

x = 5

Step-by-step explanation:

8x-9=7x+6-2x

We move all terms to the left:

8x-9-(7x+6-2x)=0

We add all the numbers together, and all the variables

8x-(5x+6)-9=0

We get rid of parentheses

8x-5x-6-9=0

We add all the numbers together, and all the variables

3x-15=0

We move all terms containing x to the left, all other terms to the right

3x=15

x=15/3

x = 5
