Question

11х-3=-3-12х -2х+4=0,5х-21

Answer 1

11х - 3 = -3 - 12х                      -2х + 4 = 0,5х - 21

11х + 12х = 3 - 3                       -2х - 0,5х = -21 - 4

23х = 0                                    -2,5х = -25

х = 0 : 23                                  х = -25 : (-2,5)

х = 0                                         х = 10

Answer 2

It looks like you have two equations with variables $x$ that you'd like to solve for. Let's solve them step by step.

Equation 1: $11x - 3 = -3 - 12x$ First, let's simplify the equation by combining like terms: $11x + 12x = -3 + 3$ $23x = 0$ Now, divide both sides by 23 to solve for $x$: $x = 0$

Equation 2: $-2x + 4 = 0.5x - 21$ First, let's move all the $x$ terms to one side of the equation and the constant terms to the other side: $-2x - 0.5x = -21 - 4$ $-2.5x = -25$ Now, divide both sides by -2.5 to solve for $x$: $x = 10$

So, the solutions for the given equations are $x = 0$ and $x = 10$.
