Question

1)18000+300+×=20000; 2) 75900-у=45000+5000

Answer 1

Ответ:

Пошаговое объяснение:

1) 18000+300+х=20000

   18300+х=20000

   18300-20000+х=0

   -1700+х=0

   х=1700

2) 7900-y=45000+5000

   7900-y=50000

   -y= 50000-7900

   y= -42100

Answer 2

It seems like you have two equations with variables that you want to solve for. Let's solve them one by one:

Equation 1:
18000 + 300 + x = 20000

To solve for x, follow these steps:

1. Subtract 18000 and 300 from both sides of the equation: x = 20000 - 18000 - 300 x = 2000 - 300 x = 1700

So, the solution for Equation 1 is x = 1700.

Equation 2:
75900 - y = 45000 + 5000

To solve for y, follow these steps:

1. Add 45000 and 5000 on the right side of the equation: 75900 - y = 50000

2. Subtract 75900 from both sides of the equation: -y = 50000 - 75900 -y = -25900

3. Multiply both sides by -1 to solve for y: y = 25900

So, the solution for Equation 2 is y = 25900.
