Answer:
The number 11 is not a solution for the given equation.
Step-by-step explanation:
We are given an equation with one variable. We can use simplifying processes to solve the equation.
![3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}](https://tex.z-dn.net/?f=3%28x%2B6%29%3D4x%20%5C%20%5C%20%20%5Ctext%7BDistribute%20the%203%20through.%7D%5C%5C3x%20%2B%2018%20%3D%204x%5C%20%5C%20%5C%20%5Ctext%7BFlip%20the%20equation.%7D%5C%5C4x%20%3D%203x%20%2B%2018%20%5C%20%5C%20%5C%20%5Ctext%7BSubtract%203x%20from%20both%20sides.%7D%5C%5C%5Csmall%5Cboxed%7B%5Cbold%7Bx%20%3D%2018%7D%7D)
We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.
![3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}](https://tex.z-dn.net/?f=3%2811%20%2B%206%29%20%3D%204%2811%29%5C%5C33%20%2B%2018%20%3D%2044%5C%5C%5Csmall%5Cboxed%7B%5Cbold%7B51%20%5Cneq%2044%7D%7D)
Therefore, 11 is not a solution for the given equation.
