Question

1. 6) a) x – 459 = 198; B) x 80 = 1 920; x + 406 = 1 894; r) 200: x = 25.​

Answer 1

Ответ:

а) 459+198=657, х=657

в) 1920÷80=24, х=24

1894-406=1488, х=1488

200÷25=8, х=8

Answer 2

Let's solve each of these equations step by step:

a) x - 459 = 198

To isolate x, add 459 to both sides of the equation:

x - 459 + 459 = 198 + 459

x = 657

b) x / 80 = 1,920

To isolate x, multiply both sides of the equation by 80:

(x / 80) * 80 = 1,920 * 80

x = 153,600

c) x + 406 = 1,894

To isolate x, subtract 406 from both sides of the equation:

x + 406 - 406 = 1,894 - 406

x = 1,488

r) 200 / x = 25

To isolate x, multiply both sides of the equation by x:

(200 / x) * x = 25 * x

200 = 25x

Now, divide both sides by 25 to find x:

200 / 25 = 25x / 25

8 = x

So, the solutions to the equations are:

a) x = 657 b) x = 153,600 c) x = 1,488 r) x = 8
