Question

1) -2(x + 3) = 2x – 1;3) -(3x – 4) = 3x – 8;​

Answer 1

1)-2(х+3)=2х-1
-2х-6=2х-1
-2х-2х=-1+6
-4х=5
Х=-1,25
2)-(3х-4)=3х-8
-3х+4=3х-8
-3х-3х=-8-4
-6х=-12
Х=2

Answer 3

To solve the equations, you'll want to isolate the variable x. Let's solve each equation step by step:

1. -2(x + 3) = 2x - 1

First, distribute the -2 on the left side of the equation:

-2x - 6 = 2x - 1

Now, let's get all the x terms on one side and the constants on the other side:

-2x - 2x = 1 - 6

-4x = -5

Now, divide both sides by -4 to isolate x:

x = (-5) / (-4)

x = 5/4

So, the solution to the first equation is x = 5/4.

2. -(3x - 4) = 3x - 8

Again, distribute the negative sign on the left side of the equation:

-3x + 4 = 3x - 8

Now, move the variable terms to one side and the constants to the other side:

-3x - 3x = -8 - 4

-6x = -12

Now, divide both sides by -6 to isolate x:

x = (-12) / (-6)

x = 2

So, the solution to the second equation is x = 2.
