Question

6241) 6x + 8x – 7x = 7142) 23x - 19x + 5x = 1827;​

Answer 1

1) 6x + 8x – 7x = 714

7x = 714

x = 714 : 7

x = 102

2) 23x - 19x + 5x = 1827

9x = 1827

x = 1827 : 9

x = 203

Answer 2

Пошаговое объяснение:

1)

6х+8х-7х=714

7х=714

Х=714:7

Х=102

2)

23х-19х+5х=1827

9х=1827

Х=1827:9

Х=203

Answer 3

Let's solve these equations step by step:

1. 6x + 8x - 7x = 71

First, combine like terms on the left side of the equation:

(6x + 8x) - 7x = 14x - 7x = 7x

So the equation becomes:

7x = 71

Now, to solve for x, divide both sides of the equation by 7:

(7x)/7 = 71/7

x = 10

So the solution to the first equation is x = 10.

2. 23x - 19x + 5x = 1827

Combine like terms on the left side of the equation:

(23x - 19x + 5x) = (23x - 19x) + 5x = 4x + 5x = 9x

So the equation becomes:

9x = 1827

Now, to solve for x, divide both sides of the equation by 9:

(9x)/9 = 1827/9

x = 203

So the solution to the second equation is x = 203.
