Answer:

The answer is A.

Step-by-step explanation:

First, you have to add 2 to both sides, to get rid of the -2 on the left side :

9x - 2 = 2x + 12

9x - 2 + 2 = 2x + 12 + 2

9x = 2x + 14

Next, you have to subtract 2x to both sides, to make all the x terms to one side and then, solve it :

9x - 2x = 2x + 14 - 2x

7x = 14

x = 14 \div 7

x = 2

Rewrite 2 5/8 with a denominator of 24
gladu [14]

Answer:

63/24

Step-by-step explanation:

First you change the whole 2 to have a fraction of 48/24.

Next you have change 5/8 so its denominator has a 24. So you multiple the 8 by 3 to get 5/24. But then you have to multiply the 5 by 3 also so it is still the same fraction just bigger and you get 15/24. Now add the 15/24 with 48/24 to get 63/24.

Hope this helps!

If (x, 9) is a solution to 5x - 2y = 12, what is the value of x ?
lina2011 [118]
X= 6


Explanation:

y=9 so rewrite the equation like this:


5x-2(9)=12

Multiply -2 by 9:


5x-18=12

Cancel out the -18:


5x-18=12
+18 +18


5x=30


Divide both numbers by 5:


5x/5 = 30/5


As an answer, you will get x=6:

Hope this helped:)
