The equation is 2 by 3 x -8 is equal to 4 by 8

2 X by 3 is equal to 4 + 6 all by 8

X equal to 4.2

Answer:

The correct answer is that the number is 12.75.

Step-by-step explanation:

While this question is written in a convoluted manner, it is asking you to decrease 2/3x by 8. This is the expression for that.

2/3x - 8

And it is saying that it is equal to 4/8, which can be simplified to 1/2.

2/3x - 8 = 1/2

Now we can solve for the x.

2/3x - 8 = 1/2

2/3x = 17/2

x = 12.75

You haven't included enough information for the question, but assuming that a and b are the same then a is 4 and b is 4

Solving equations with variables on both sides <br><br><br> 7+9x=6x-2

katrin2010 [14]

Answer:

Here

Step-by-step explanation:

We move all terms to the left:

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

We get rid of parentheses

9x-6x+2+7=0

We add all the numbers together, and all the variables

3x+9=0

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

3x=-9

x=-9/3

x=-3

Answer:

9a+6b

Step-by-step explanation:
