Question

1) x-8=16-8x 2) 3x-2=(x+1)-4​

Answer 1

Ответ:

1) х-8=16-8х

х+8х=16+8

9х=24

х=8/3

------------------------------

2) 3х-2=(х+1)-4

3х-2=х+1-4

3х-2=х-3

3х-х=-3+2

2х=-1

х=-1/2

Answer 2

Let's solve the two equations one by one:

1. x - 8 = 16 - 8x

To solve this equation, we'll start by simplifying both sides and combining like terms:

x + 8x = 16 + 8

Combining the x terms gives us:

9x = 24

To isolate x, we divide both sides of the equation by 9:

(9x)/9 = 24/9

Simplifying further:

x = 8/3

So the solution to the equation is x = 8/3.

2. 3x - 2 = (x + 1) - 4

Let's simplify both sides of the equation by combining like terms:

3x - 2 = x + 1 - 4

Combining the x terms and the constant terms:

2x - 2 = -3

To isolate x, we can add 2 to both sides of the equation:

2x - 2 + 2 = -3 + 2

Simplifying further:

2x = -1

Finally, divide both sides of the equation by 2:

(2x)/2 = -1/2

Simplifying gives us:

x = -1/2

So the solution to the equation is x = -1/2.
