Question

(3187+х)-2456=18593 57:(х:28)=19

Answer 1

× = 17862

×=84

.........

Answer 2

(3187+х)-2456=18593

3178+х=18593+2456

3187+х=21049

х=21049-3187

х=17862

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

57: (х:28) = 19

х:28=57:19

х:28=3

х=28*3

х=84

Answer 3

Let's solve the equations one by one:

1. (3187 + x) - 2456 = 18593

To solve this equation, we'll simplify and isolate the variable x.

3187 + x - 2456 = 18593 x - 2456 = 18593 - 3187 x - 2456 = 15406 x = 15406 + 2456 x = 17862

Therefore, the solution for the first equation is x = 17862.

2. 57 / (x / 28) = 19

To solve this equation, we'll simplify and isolate the variable x.

57 / (x / 28) = 19

To eliminate the fraction, we'll multiply both sides of the equation by (x / 28):

57 = 19 * (x / 28)

Now, let's isolate x:

57 = (19 * x) / 28

Multiplying both sides of the equation by 28:

28 * 57 = 19 * x

1596 = 19 * x

Dividing both sides of the equation by 19:

x = 1596 / 19

x ≈ 84

Therefore, the solution for the second equation is x ≈ 84.

Final solutions: x = 17862 (from the first equation) x ≈ 84 (from the second equation)
