We add all the numbers together, and all the variables
3x-(4(+x+1/2))-7=0
We multiply all the terms by the denominator
3x*2))-(4(+x+1-7*2))=0
We add all the numbers together, and all the variables
3x*2))-(4(x-13))=0
We add all the numbers together, and all the variables
3x*2))-(4(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
