СРОЧНОО ПОМОГИТЕ 0,6(4x-3) -2,1(x-5)9y-5(4x-3)-2(-5,2-3,1c)-(2,4c-6,4)(a+4,6)-(a+9,8)-(9,4+x-4)-(-a-b+b,1)​

Answer 1

4(x-3)=x+6

4x-12=x+6

4x-x=6+12

3x=18

x=18:3

x=6

4-6(x+2)=3-5x

4-6x-12=3-5x

-8-6x=3-5x

-6x+5x=3+8

-x=11

x=-11

(5x+8)-(8x+14)=9

5x+8-8x-14=9

-3x-6=9

-3x=6+9

-3x=15

x=- 5

2,7+3y=9(y-2,1)

2.7+3y=9y-18.9

3y-9y=-18.9-2.7

-6y=-21.6

y=3.6

0,3(8-3y)=3,2-0,8(y-7)

2.4-0.9y=3.2-0.8y+5.6

-0.9y+0.8y=8.8-2.4

-0.1y=6.4

y=-64

5,6(1,3x-1,5)=3x+3  1/3

7,28x-8,4=3x+3  1/3

7.28x-3x=3  1/3 + 8.4

4.28x=10/3+8.4|*3

12,84x=10+25,2

x=2  952/1284 = 2  238 / 321  

Answer 2

To solve the given expression, let's simplify it step by step:

1. Distribute the terms inside the parentheses: - Distributing 0.6 to (4x - 3) gives 2.4x - 1.8. - Distributing -2.1 to (x - 5) gives -2.1x + 10.5. - Distributing -5 to (4x - 3) gives -20x + 15. - Distributing -2 to (-5.2 - 3.1c) gives 10.4 + 6.2c. - Distributing -(2.4c - 6.4) gives -2.4c + 6.4. - Distributing (a + 4.6) gives a + 4.6. - Distributing (a + 9.8) gives a + 9.8. - Distributing (9.4 + x - 4) gives 13.4 + x. - Distributing -(-a - b + b.1) gives a + b - b.1.

2. Combine like terms: - Combine the terms with x: 2.4x - 20x = -17.6x. - Combine the constant terms: -1.8 + 15 + 10.5 + 10.4 + 6.4 + 4.6 + 9.8 + 13.4 = 59.9. - Combine the terms with c: 6.2c - 2.4c = 3.8c. - Combine the terms with a: a + a = 2a. - Combine the terms with b: -b + b = 0.

3. Simplify the expression: - The simplified expression is -17.6x + 59.9 + 3.8c + 2a.
