Answer: x=54/7

Explanation:

To find the value of x, we need to use algebraic properties to isolate x.

12x-36=5x+18 [subtract both sides by 5x]

7x-36=18 [add both sides by 36]

7x=54 [divide both sides by 7]

x=54/7

Now, we know that x=54/7.

Answer:


x = (54)/(7)

Explanation:

(12x − 36) = 5x + 18

First of all remove the parenthesis

That's

12x - 36 = 5x + 18

Next subtract 5x from both sides of the equation

We have

12x - 5x - 36 = 5x - 5x + 18

7x - 36 = 18

Add 36 to both sides of the equation

That's

7x + 36 - 36 = 18 + 36

7x = 54

Divide both sides by 7


(7x)/(7) = (54)/(7)

We have the final answer as


x = (54)/(7)

Hope this helps you
