18x-(7/2)x=158

We move all terms to the left:

18x-(7/2)x-(158)=0

Domain of the equation: 2)x!=0We add all the numbers together, and all the variables

x!=0/1

x!=0

x∈R

18x-(+7/2)x-158=0

We multiply parentheses

-7x^2+18x-158=0

a = -7; b = 18; c = -158;

Δ = b^{2}-4ac

Δ = 18^{2}-4·(-7)·(-158)

Δ = -4100

Delta is less than zero, so there is no solution for the equation
