-2=6/7*x
We move all terms to the left:
-2-(6/7*x)=0
Domain of the equation: 7*x)!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
-(+6/7*x)-2=0
We get rid of parentheses
-6/7*x-2=0
We multiply all the terms by the denominator
-2*7*x-6=0
Wy multiply elements
-14x*x-6=0
Wy multiply elements
-14x^2-6=0
a = -14; b = 0; c = -6;
Δ = b2-4ac
Δ = 02-4·(-14)·(-6)
Δ = -336
Delta is less than zero, so there is no solution for the equation
