Question

1) 3(х-5)-5(х-2)=-322) х/3-2х/2=1/63) (х-5)=6​

Answer 1

Ответ:

1) 3х-15-5х+10=-32

-2х-5=-32

-2х=-32+5

-2х=-17

-х=-8.5

х=8.5

3) 6(х-5)=0

6х - 35=0

6х=35

х= 5.8

Answer 2

Let's solve each of these equations step by step:

1. 3(x-5) - 5(x-2) = -32

First, distribute the constants inside the parentheses:

3x - 15 - 5x + 10 = -32

Now, combine like terms:

(3x - 5x) + (-15 + 10) = -32

-2x - 5 = -32

Now, add 5 to both sides of the equation to isolate the variable:

-2x = -32 + 5

-2x = -27

Finally, divide both sides by -2 to solve for x:

x = -27 / -2 x = 27/2 x = 13.5

So, the solution to this equation is x = 13.5.

2. (x/3) - (2x/2) = 1/6

First, simplify the fractions:

(x/3) - (x) = 1/6

Now, find a common denominator, which is 6:

(2x/6) - (6x/6) = 1/6

Now, combine the fractions:

(2x - 6x)/6 = 1/6

-4x/6 = 1/6

Now, multiply both sides by 6 to isolate the variable:

-4x = 1

Finally, divide both sides by -4 to solve for x:

x = 1 / -4 x = -1/4

So, the solution to this equation is x = -1/4.

3. (x - 5) = 6

Simply add 5 to both sides of the equation to isolate the variable:

x - 5 + 5 = 6 + 5

x = 11

So, the solution to this equation is x = 11.
