Question

Решите уравнения : первое 18-16х=-30х-10 второе -7х+2=3х-1 третье 10-2х=12+х четвёртое 6х-19=-2х-15 пятое 0,2x+3,4=0,6x-2,6 и последнее 5/6х+12=1/4х-2 Заранее спасибо!

Answer 1

18-16х=-30х-10
-16х+30х=-10-18
14х=-28
х=-2
-7х+2=3х-1
-7х-3х=-1-2
-10х=-3
х=0,3
10-2х=12+х
-2х-х=12-10
-3х=2
х=(тут разве что дробью, по-другому никак) -2/3
6х-19=-2х-15
6х+2х=19-15
8х=4
х=0,5
0,2х+3,4=0,6х-2,6
0,2х-0,6х=-2,6-3,4
-0,4х=-6
х=15
5/6х+12=1/4х-2
5/6х-1/4х=-2-12
выносим общий знаменатель 12:
10х-3х/12=-14
7х/12=-14
х=-24
Вроде так :)
Если помогла, то поставь ответ лучшим, пожалуйста )

Answer 2

1) 18-16х=-30х-10
-16х+30х=-10-18
14х=-28
х=-2
2)-7х-3х=-1-2
-10х=-3
х=0,3
3)-2х-х=12-10
-3х=2
х=2/3
4)6х+2х=-15+19
8х=4
х=0,5
5)0,2х-0,6х=-2,6-3,4
-0,4х=-6
х=15
6) 5/6х-1/4х=-2-12
0,7х=-14
х=-20

Answer 3

Solving the Equations:

First Equation: The first equation is 18 - 16x = -30x - 10.

To solve for x: 18 - 16x = -30x - 10 Add 30x to both sides: 18 + 14x = -10 Subtract 18 from both sides: 14x = -28 Divide by 14: x = -2

Second Equation: The second equation is -7x + 2 = 3x - 1.

To solve for x: -7x + 2 = 3x - 1 Add 7x to both sides: 2 = 10x - 1 Add 1 to both sides: 3 = 10x Divide by 10: x = 0.3

Third Equation: The third equation is 10 - 2x = 12 + x.

To solve for x: 10 - 2x = 12 + x Add 2x to both sides: 10 = 12 + 3x Subtract 12 from both sides: -2 = 3x Divide by 3: x = -2/3

Fourth Equation: The fourth equation is 6x - 19 = -2x - 15.

To solve for x: 6x - 19 = -2x - 15 Add 2x to both sides: 8x - 19 = -15 Add 19 to both sides: 8x = 4 Divide by 8: x = 0.5

Fifth Equation: The fifth equation is 0.2x + 3.4 = 0.6x - 2.6.

To solve for x: 0.2x + 3.4 = 0.6x - 2.6 Subtract 0.2x from both sides: 3.4 = 0.4x - 2.6 Add 2.6 to both sides: 6 = 0.4x Divide by 0.4: x = 15

Sixth Equation: The sixth equation is 5/6x + 12 = 1/4x - 2.

To solve for x: 5/6x + 12 = 1/4x - 2 Subtract 1/4x from both sides: 5/6x - 1/4x + 12 = -2 Combine like terms: 1/12x + 12 = -2 Subtract 12 from both sides: 1/12x = -14 Multiply by 12: x = -168
