I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a

Solve for x.<br> 3(2x + 5) = 33
Umnica [9.8K]

Answer:

x = 3

Step-by-step explanation:
