Answer 1

Ответ:

Пошаговое объяснение:

3(x-7) + 5x = 3x-21+5x = 8x-21

5(4-3x)+8x = 20-15x+8x = 20-7x

(y-4)*2+10y = 2y-8+10y = 12y-8

(2y+5)*4-11y = 8y+20-11y = -3y+20 = 20-3y

4x+2(0,5x+3) = 4x+x+6 = 5x+6

6x-3(x-7) = 6x-3x+21 = 3x+21 = 3(x+7)

Answer 2

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

1. 3(x-7) + 5x = ? Start by distributing the 3 on the left side of the equation: 3x - 21 + 5x = ?

   Combine like terms on the left side: 3x + 5x - 21 = 8x - 21

   So, 3(x-7) + 5x simplifies to 8x - 21.

2. 5(4-3x) + 8x = ? Start by distributing the 5 on the left side of the equation: 20 - 15x + 8x = ?

   Combine like terms on the left side: 20 - 7x = 13 - 7x

   So, 5(4-3x) + 8x simplifies to 13 - 7x.

3. (y-4)•2 + 10y = ? Start by distributing the 2 on the left side of the equation: 2y - 8 + 10y = ?

   Combine like terms on the left side: 2y + 10y - 8 = 12y - 8

   So, (y-4)•2 + 10y simplifies to 12y - 8.

4. (2y+5)•4 - 11y = ? Start by distributing the 4 on the left side of the equation: 8y + 20 - 11y = ?

   Combine like terms on the left side: 8y - 11y + 20 = -3y + 20

   So, (2y+5)•4 - 11y simplifies to -3y + 20.

5. 4x + 2(0.5x+3) = ? Start by distributing the 2 on the right side of the equation: 4x + x + 6 = ?

   Combine like terms on the left side: 4x + x + 6 = 5x + 6

   So, 4x + 2(0.5x+3) simplifies to 5x + 6.

6. 6x - 3(x-7) = ? Start by distributing the -3 on the right side of the equation: 6x - 3x + 21 = ?

   Combine like terms on the left side: 6x - 3x + 21 = 3x + 21

   So, 6x - 3(x-7) simplifies to 3x + 21.
