Question

(4,5x+3,6)*(-19,6)=0 (1,2х+16,8)*-13,1=0 -32,7*(0,1х+6,3)=0 -15.1/13*(1,9χ+5,7)=0

Answer 1

(4,5x+3,6)*(-19,6)=0
-88,2х-70,56=0
-88,2х=70,56
х=-0,8
или 4,5x+3,6=0
4,5x=-3,6
х=-0,8

(1,2х+16,8)*-13,1=0
15,72х+220,08=0
15,72х=-220,08
х=-14
1,2х+16,8=0
1,2х=-16,8
х=-14

-32,7*(0,1х+6,3)=0
0,1х+6,3=0
0,1х=-6,3
х=63

-15.1/13*(1,9χ+5,7)=0
1,9χ=-5,7
х=-3

Answer 2

To solve each equation for the variable 'x', we need to isolate 'x' on one side of the equation. Let's go through each one step by step:

1. (4.5x + 3.6) * (-19.6) = 0

To solve this equation, set each factor to zero and solve for 'x':

4.5x + 3.6 = 0 4.5x = -3.6 x = -3.6 / 4.5 x = -0.8

2. (1.2x + 16.8) * (-13.1) = 0

Similarly, set each factor to zero and solve for 'x':

1.2x + 16.8 = 0 1.2x = -16.8 x = -16.8 / 1.2 x = -14

3. -32.7 * (0.1x + 6.3) = 0

Now, divide both sides by -32.7 to isolate the expression within the parentheses:

0.1x + 6.3 = 0 0.1x = -6.3 x = -6.3 / 0.1 x = -63

4. -15.1 / 13 * (1.9x + 5.7) = 0

First, divide both sides by -15.1/13:

1.9x + 5.7 = 0 1.9x = -5.7 x = -5.7 / 1.9 x = -3

So, the solutions for each equation are:

1. x = -0.8
2. x = -14
3. x = -63
4. x = -3
