Answer:
6*7=42
Step-by-step explanation:
The way we approach a problem like this is by using a technique called "collecting like terms".
This means that we want to put all of the values with an "x" on one side and all of the normal numbers on the other. For this particular problem we can do this as follows:
5x - 6 = x + 12
Now move the (- 6) to the right side of the equation by adding 6 to both sides:
=> 5x = x + 12 + 6
Now move the (x) to the left side of the equation by subtracting (x) from both sides:
=> 5x - x = 12 + 6
Now perform the simple arithmetic on both sides:
=> 4x = 18
Now remove the 4 from in front of the (x) by multiplying the whole equation by (1/4)
=> x = 18/4
Therefore to make your open sentence true, x must equal 18/4, or to simplify, 9/2, or as a decimal, 4.5. I hope this helped, and remember to try and understand not just the answer, but the maths involved in getting to the answer too :))

How to do integers operations?
Integers are whole numbers, both positive and negative. You can perform four basic math operations on them: addition, subtraction, multiplication, and division. When you add integers, remember that positive integers move you to the right on the number line and negative integers move you to the left on the number line
Cómo hacer operaciones con números enteros?
Los enteros son números enteros, tanto positivos como negativos. Puede realizar cuatro operaciones matemáticas básicas con ellos: suma, resta, multiplicación y división. Cuando sume números enteros, recuerde que los números enteros positivos lo mueven hacia la derecha en la recta numérica y los enteros negativos lo mueven hacia la izquierda en la recta numérica.
