Question

14+5х=5х+3х 3а+5=8а-15 36+2х=5х+1,2

Answer 1

Ответ:

Пошаговое объяснение:

1)14=3х

х=14/3

2\)

5а=20

а=4

3)  3х=34,5

х=11,5

Answer 2

Пошаговое объяснение:

14+5х=8х

5х-8х=-14

-3х=-14

х=4,6

3а-8а=-15-5

-5а=-20

а=4

2х-5х=1,2-36

-3х=-34,8

х=11,6

Answer 3

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

1. 14 + 5x = 5x + 3x

Combine like terms: 14 + 5x = 8x

Now, isolate the variable x on one side of the equation: Subtract 5x from both sides: 14 + 5x - 5x = 8x - 5x 14 = 3x

Finally, solve for x by dividing both sides by 3: x = 14/3

2. 3a + 5 = 8a - 15

Combine like terms: 3a + 5 = 8a - 15

Now, isolate the variable a on one side of the equation: Subtract 3a from both sides: 3a - 3a + 5 = 8a - 3a - 15 5 = 5a - 15

Next, add 15 to both sides to further isolate the variable: 5 + 15 = 5a - 15 + 15 20 = 5a

Finally, solve for a by dividing both sides by 5: a = 20/5 a = 4

3. 36 + 2x = 5x + 1.2

First, let's move all the x terms to one side of the equation and the constants to the other side: 36 + 2x - 2x = 5x - 2x + 1.2 36 = 3x + 1.2

Now, isolate the variable x on one side of the equation: Subtract 1.2 from both sides: 36 - 1.2 = 3x + 1.2 - 1.2 34.8 = 3x

Finally, solve for x by dividing both sides by 3: x = 34.8/3 x ≈ 11.6

So, the solutions to the given equations are:

1. x ≈ 4.67
2. a = 4
3. x ≈ 11.6
