Start with
![2(x-3)+9=3(x+1)+x](https://tex.z-dn.net/?f=2%28x-3%29%2B9%3D3%28x%2B1%29%2Bx)
Expand both parentheses by multiplying both terms by the number outside:
![2x-6+9 = 3x+3+x](https://tex.z-dn.net/?f=2x-6%2B9%20%3D%203x%2B3%2Bx)
Sum like terms:
![2x+3 = 4x+3](https://tex.z-dn.net/?f=2x%2B3%20%3D%204x%2B3)
Simplify the "+3" on both sides:
![2x = 4x](https://tex.z-dn.net/?f=2x%20%3D%204x)
Subtract 2x from both sides:
![2x=0](https://tex.z-dn.net/?f=2x%3D0)
Divide both sides by 2:
![x=0](https://tex.z-dn.net/?f=x%3D0)
Just multiply directly numerator with numerator and denominator with denominator

Answer:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference.
