Question

2х-4=-52-(х+9)=33(х-1)=6-4(5+4х)=8х-33(х-5)-3х=6-7х​

Answer 1

Ответ:

2x-4=-5

2x=4+5

2x=9

2-(x+9)=3

2-x-9=3

-7-x=3

-x=3+7

-x=-10

x=-10

3(x-1)=6

x-1=2

x=2+1

x=3

-4(5+4x)=8x-3

-20-16x=8x-3

-16x-8x=-3+20

-24x=17

x=17/24

x=-0,7083

3(x-5)-3x=6-7x

3x-15-18x-7x

-22x-15

Answer 3

Let's solve each equation step by step:

1. 2x - 4 = -52 To solve this equation, we need to isolate x on one side of the equation. First, add 4 to both sides: 2x = -52 + 4 2x = -48 Now, divide both sides by 2 to get the value of x: x = -48 / 2 x = -24

2. • (x + 9) = 33 To solve this equation, start by distributing the negative sign to both terms inside the parentheses:

• x - 9 = 33 Next, add 9 to both sides:
• x = 33 + 9
• x = 42 Now, multiply both sides by -1 to isolate x: x = -42

3. (x - 1) = 6 To solve this equation, add 1 to both sides: x = 6 + 1 x = 7

4. 6 - 4(5 + 4x) = 8x - 33 First, simplify the expression inside the parentheses: 6 - 4(5 + 4x) = 6 - 20 - 16x Now, combine like terms: 6 - 20 - 16x = 8x - 33 Next, bring all the x terms to one side and the constant terms to the other side: -16x - 8x = -33 - 6 + 20 -24x = -19 Finally, divide both sides by -24 to get the value of x: x = -19 / -24 x = 19/24

5. (x - 5) - 3x = 6 - 7x First, simplify the equation by removing the parentheses: x - 5 - 3x = 6 - 7x Now, combine like terms: -x - 5 = 6 - 7x Next, bring all the x terms to one side and the constant terms to the other side: -x + 7x = 6 + 5 6x = 11 Finally, divide both sides by 6 to find the value of x: x = 11 / 6

In conclusion, the solutions to the given equations are: x = -24 x = -42 x = 7 x = 19/24 x = 11/6
