-4+3x=8x+5 линейные уравнения нийти корень уравнения

Answer 1

$-4+3x=8x+5$
$-4-5=8x-3x$
$-9=5x$
$-\frac{9}{5} = x$
$-1,8 = x$

Answer 2

To find the root of the linear equation $-4 + 3x = 8x + 5$, we need to isolate the variable $x$ on one side of the equation.

Let's solve the equation step by step:

Step 1: Move the variable terms to one side and the constant terms to the other side. Subtract 8x from both sides: $-4 + 3x - 8x = 8x + 5 - 8x$

Simplify: $-5x - 4 = 5$

Step 2: Move the constant term to the opposite side. Add 4 to both sides: $-5x - 4 + 4 = 5 + 4$

Simplify: $-5x = 9$

Step 3: Isolate the variable by dividing both sides by the coefficient of $x$. $\frac{-5x}{-5} = \frac{9}{-5}$

Simplify: $x = -\frac{9}{5}$

So, the root of the linear equation is $x = -\frac{9}{5}$ or $x = -1.8$.
