0.1x=0.2(x+2)3x+15=3(x+5)

Solution for 0.1x=0.2(x+2)3x+15=3(x+5) equation:

0.1x=0.2(x+2)3x+15=3(x+5)

We move all terms to the left:

0.1x-(0.2(x+2)3x+15)=0


We calculate terms in parentheses: -(0.2(x+2)3x+15), so:

0.2(x+2)3x+15

We multiply parentheses

0x^2+0x+15

We add all the numbers together, and all the variables

x^2+x+15

Back to the equation:

-(x^2+x+15)


We get rid of parentheses

-x^2+0.1x-x-15=0

We add all the numbers together, and all the variables

-1x^2-0.9x-15=0

a = -1; b = -0.9; c = -15;
Δ = b2-4ac
Δ = -0.92-4·(-1)·(-15)
Δ = -59.19
Delta is less than zero, so there is no solution for the equation
