Answer 2

Ответ:1) -7x=28

x=28÷(-7)

x= -4

2) 0.6x= -2,4

x=-2.4 ÷ 0,6

x= -4

3) -1,8x= -5,4

x= -5,4 ÷ -1,8

x = 3 минус на минус даёт плюс

4) 1/9÷x= -5/18

x= 1/9 ÷ (-5/18)

x= - 2/5

6)- 2 5/6x= -17/18

x= - 17/18 ÷( -2 5/6)

x=-17/18 ÷ - 17/6

x= 1/3

Answer 3

It looks like you've provided a list of equations. It seems like you're looking for solutions to each equation. I'll go through each equation and solve for x:

1. -7x = 28 Divide both sides by -7: x = -28 / -7 x = 4

2. 0.6x = -2.4 Divide both sides by 0.6: x = -2.4 / 0.6 x = -4

3. -1.8x = -5.4 Divide both sides by -1.8: x = -5.4 / -1.8 x = 3

4. 1/9 : x = -5/18 Multiply both sides by x to solve for x: x * (1/9) = -5/18 x/9 = -5/18 Multiply both sides by 9: x = -5/18 * 9 x = -5/2

5. -5/6x = 1 + 7 Add 1 and 7 on the right side: -5/6x = 8 Divide both sides by -5/6: x = 8 / (-5/6) x = -48/5

6. -2 5/6 x = -17/18 First, convert the mixed number to an improper fraction: -2 5/6 = -17/6 Now solve for x: -17/6 x = -17/18 Divide both sides by -17/6: x = -17/18 * 6 / -17 x = 1/18

So, the solutions for each equation are:

1. x = 4
2. x = -4
3. x = 3
4. x = -5/2
5. x = -48/5
6. x = 1/18
