8(-1+x)+3=2(x-51/2
We move all terms to the left:
8(-1+x)+3-(2(x-51/2)=0
We add all the numbers together, and all the variables
8(x-1)-(2(+x-51/2)+3=0
We multiply parentheses
8x-(2(+x-51/2)+3-8=0
We multiply all the terms by the denominator
8x*2)+3-8-(2(+x-51=0
Wy multiply elements
16x^2=0
a = 16; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·16·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
