Question

1/3X=2. X+4=9 X+5=5 7X=10 X+2=_4

Answer 1

Ответ:

$\frac{1}{3} x = 2 \\ x = 2 \times 3 \\ x = 6$

$x + 4 = 9 \\ x = 9 - 4 \\ x = 5$

$x + 5 = 5 \\ x = 5 - 5 \\ x = 0$

$7x = 10 \\ x = \frac{10}{7}$

$x + 2 = 4 \\ x = 4 - 2 \\ x = 2$

$x + 2 = - 4 \\ x = - 4 - 2 \\ x = - 6$

Answer 2

Пошаговое объяснение:

$\frac{1}{3x} = 2 \\ 3x = \frac{1}{2} \\ x = \frac{1}{2} \div 3 \\ x = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6}$

x+4=9

x=9-4=5

x+5=5

x=5-5=0

7x=10

x=10/7

x+2=4

x=4-2=2

Answer 3

Let's solve each equation step by step:

1. 1/3X = 2 To solve for X, we need to isolate X on one side of the equation. To do this, we'll multiply both sides by 3 to get rid of the fraction: (1/3)X * 3 = 2 * 3 X = 6

2. X + 4 = 9 Subtract 4 from both sides to isolate X: X + 4 - 4 = 9 - 4 X = 5

3. X + 5 = 5 Subtract 5 from both sides to isolate X: X + 5 - 5 = 5 - 5 X = 0

4. 7X = 10 To solve for X, we'll divide both sides by 7: 7X / 7 = 10 / 7 X = 10/7 or 1.43 (rounded to two decimal places)

5. X + 2 = -4 Subtract 2 from both sides to isolate X: X + 2 - 2 = -4 - 2 X = -6

So the solutions for the respective equations are:

1. X = 6
2. X = 5
3. X = 0
4. X = 10/7 or approximately 1.43
5. X = -6
