Answer 1

а) 37х=259

х=259:37

х=7

б) 252:у=21

у=252:21

у=12

в) z:18=6

z=6*18

z=108

г) (3в+b)•12=840

4b*12=840

48b=840

b=840:48

b=17,5

д) 14(р-30)=630

p-30=630:14

p-30=45

p=45+30

p=75

е) (43-s)•17=289

43-s=289:17

43-s=17

s=43-17

s=26

Г и Е не очень понятно, надеюсь , что будет правильно. Пиши задание внимательней.

Answer 2

Solving Equations with Fractions:

Solving equations with fractions involves isolating the variable on one side of the equation. Let's solve the given equations step by step.

a) 37x = 259:

To solve this equation, we need to isolate the variable x. We can do this by dividing both sides of the equation by 37:

37x / 37 = 259 / 37

Simplifying the equation gives us:

x = 7

b) 252 / y = 21:

To solve this equation, we need to isolate the variable y. We can do this by multiplying both sides of the equation by y:

252 / y * y = 21 * y

Simplifying the equation gives us:

252 = 21y

Next, we divide both sides of the equation by 21 to solve for y:

252 / 21 = 21y / 21

Simplifying the equation gives us:

y = 12

c) z / 18 = 6:

To solve this equation, we need to isolate the variable z. We can do this by multiplying both sides of the equation by 18:

z / 18 * 18 = 6 * 18

Simplifying the equation gives us:

z = 108

z = 108

d) 12(b) = 840:

To solve this equation, we need to isolate the variable b. We can do this by dividing both sides of the equation by 12:

12(b) / 12 = 840 / 12

Simplifying the equation gives us:

b = 70

e) (43 - s) * 17 - 289:

To solve this equation, we need to simplify the expression first. Let's start by simplifying the expression within the parentheses:

(43 - s) * 17 - 289 = (43 * 17 - s * 17) - 289

Simplifying further gives us:

(731 - 17s) - 289

Next, we combine like terms:

731 - 17s - 289 = 442 - 17s

Finally, we simplify the equation:

442 - 17s
