((x+7)/2)+3x=21
We move all terms to the left:
((x+7)/2)+3x-(21)=0
We add all the numbers together, and all the variables
3x+((x+7)/2)-21=0
We multiply all the terms by the denominator
3x*2)+((x+7)-21*2)=0
We add all the numbers together, and all the variables
3x*2)+((x+7)=0
Wy multiply elements
6x^2=0
a = 6; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·6·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
