70-x-x=x-((70-x)/2)

Solution for 70-x-x=x-((70-x)/2) equation:

70-x-x=x-((70-x)/2)

We move all terms to the left:

70-x-x-(x-((70-x)/2))=0

We add all the numbers together, and all the variables

-x-x-(x-((-1x+70)/2))+70=0

We add all the numbers together, and all the variables

-2x-(x-((-1x+70)/2))+70=0

We multiply all the terms by the denominator


-2x*2))-(x-((-1x+70)+70*2))=0

We add all the numbers together, and all the variables

-2x*2))-(x-((-1x+70)=0

Wy multiply elements

-4x^2=0

a = -4; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-4)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
