Помогите решить уравнения с:1) 10х+7=8х-92)53-6х=4х-173)8+2х=16+х

Answer 1

$1) 10x+7=8x-9 \\ 10x-8x=-9-7 \\ 2x=-16 \\ x=-8 \\ \\ 2)53-6x=4x-17 \\ -6x-4x=-17-53 \\ -10x=-70 \\ 10x=70 \\ x=7 \\ \\ 3)8+2x=16+x \\ 2x-x=16-8 \\ x=8$

Answer 2

1) 10х+7=8х-9
10х-8х=-9-7
2х=-16
х=8

2)53-6х=4х-17
-6х-4х=-17-53
-10х=-70
х=7


3)8+2х=16+х
2х-х=16-8
х=8

Answer 3

Решение уравнений:

1) 10x + 7 = 8x - 9

2) 53 - 6x = 4x - 17

3) 8 + 2x = 16 + x

Решение уравнения 1: To solve the equation 10x + 7 = 8x - 9, we can start by isolating the variable x on one side of the equation.

10x + 7 = 8x - 9 Subtract 8x from both sides: 10x - 8x + 7 = -9 Simplify: 2x + 7 = -9 Subtract 7 from both sides: 2x = -9 - 7 2x = -16 Finally, divide by 2: x = -16 / 2 x = -8

So, the solution to the equation 10x + 7 = 8x - 9 is x = -8.

Решение уравнения 2: Next, we'll solve the equation 53 - 6x = 4x - 17.

53 - 6x = 4x - 17 Add 6x to both sides: 53 = 10x - 17 Add 17 to both sides: 70 = 10x Divide by 10: x = 7

The solution to the equation 53 - 6x = 4x - 17 is x = 7.

Решение уравнения 3: Finally, we'll solve the equation 8 + 2x = 16 + x.

8 + 2x = 16 + x Subtract x from both sides: 8 + x = 16 Subtract 8 from both sides: x = 16 - 8 x = 8

The solution to the equation 8 + 2x = 16 + x is x = 8.

So, the solutions to the given equations are: 1) x = -8 2) x = 7 3
