Question

A) 2x + 7 = 0;6) 7x + 2 = 0;B) 8x - 4 = 0;r) 4x + 8 = 0.​

Answer 1

1) 2х + 7 = 0

2х = -7

х = -7/2 = -3 1/2

2) 7х + 2 = 0

7х = -2

х = -2/7

3) 8х - 4 = 0

8х = 4

х = 4/8

х = 1/2

4) 4х + 8 = 0

4х = -8

х = -2

Answer 2

Ответ:

Х=3,5;Х=2/7;Х=0,5;Х=-2

Answer 3

It looks like you've written a set of linear equations. To solve for 'x' in each equation, you can isolate 'x' on one side of the equation. Here are the solutions for each equation:

A)

1. 2x + 7 = 0 Subtract 7 from both sides: 2x = -7 Divide both sides by 2 to isolate 'x': x = -7/2 or x = -3.5

2. 7x + 2 = 0 Subtract 2 from both sides: 7x = -2 Divide both sides by 7 to isolate 'x': x = -2/7

B)

1. 8x - 4 = 0 Add 4 to both sides: 8x = 4 Divide both sides by 8 to isolate 'x': x = 4/8 x = 1/2

2. 4x + 8 = 0 Subtract 8 from both sides: 4x = -8 Divide both sides by 4 to isolate 'x': x = -8/4 x = -2
