Question

1)9(x)-2(x)-8=5(x) 2)7(x)-2(x)=3(x)+12

Answer 1

Ответ:

1)х=4

2)х=6

Пошаговое объяснение:

1)9х-2х-8=5х

9х-2х-5х=8

2х=8

х=4

2)7х-2х=3х+12

7х-2х-3х=12

2х=12

х=6

Answer 2

Let's solve the equations one by one:

1. 9(x) - 2(x) - 8 = 5(x)

Simplifying the equation, we have:

7x - 8 = 5x

To isolate the variable x, we'll subtract 5x from both sides:

7x - 5x - 8 = 0

2x - 8 = 0

Next, we'll add 8 to both sides:

2x = 8

Finally, divide both sides by 2:

x = 8/2

x = 4

Therefore, the solution to the equation is x = 4.

2. 7(x) - 2(x) = 3(x) + 12

Simplifying the equation, we have:

5x = 3x + 12

To isolate the variable x, we'll subtract 3x from both sides:

5x - 3x = 12

2x = 12

Next, divide both sides by 2:

x = 12/2

x = 6

Therefore, the solution to the equation is x = 6.
