Where the y is on the bottom put the one on top in for y So 3x+1(x+4)=16 The answer is 3 I believe because 16 minus 4 equals 12 12 divided by 4 equals 3
First you would fill in what you know which would be you so you would write 3x+(x+4)=16 so then you would combine like terms so you would get 4x+4=16 then you would subtract 4 from both sides giving you 4x=12 then divide be 4 on both sides and you would get x=3 for your answer
