-13+5n=7n(-6+8n)=3

Solution for -13+5n=7n(-6+8n)=3 equation:

-13+5n=7n(-6+8n)=3

We move all terms to the left:

-13+5n-(7n(-6+8n))=0

We add all the numbers together, and all the variables

5n-(7n(8n-6))-13=0


We calculate terms in parentheses: -(7n(8n-6)), so:

7n(8n-6)

We multiply parentheses

56n^2-42n

Back to the equation:

-(56n^2-42n)


We get rid of parentheses

-56n^2+5n+42n-13=0

We add all the numbers together, and all the variables

-56n^2+47n-13=0

a = -56; b = 47; c = -13;
Δ = b2-4ac
Δ = 472-4·(-56)·(-13)
Δ = -703
Delta is less than zero, so there is no solution for the equation
