2x+3((13-5x)/4)=15
We move all terms to the left:
2x+3((13-5x)/4)-(15)=0
We add all the numbers together, and all the variables
2x+3((-5x+13)/4)-15=0
We multiply all the terms by the denominator
2x*4)+3((-5x+13)-15*4)=0
We add all the numbers together, and all the variables
2x*4)+3((-5x+13)=0
Wy multiply elements
8x^2=0
a = 8; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·8·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$x=\frac{-b}{2a}=\frac{0}{16}=0$
