3x-15=(x/2)+5
We move all terms to the left:
3x-15-((x/2)+5)=0
We add all the numbers together, and all the variables
3x-((+x/2)+5)-15=0
We multiply all the terms by the denominator
3x*2)+5)-((+x-15*2)+5)=0
We add all the numbers together, and all the variables
3x*2)+5)-((x-30)+5)=0
We add all the numbers together, and all the variables
3x*2)+5)-((x=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
