Question

123+х=256.... .105:х=15.......... .204-х=15​

Answer 1

Ответ:

123+x=256

x=256-123

x=133

123+133=256

105:x=15

x=105:15

x=7

105:7=15

204-x=15

x=204-15

x=189

204-189=15

Answer 3

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

1. 123 + x = 256

To solve for x in this equation, you need to isolate x on one side. Subtract 123 from both sides:

x = 256 - 123 x = 133

So, the solution for x in the first equation is x = 133.

2. 105 / x = 15

To solve for x in this equation, you need to isolate x on one side. Multiply both sides by x:

105 = 15 * x

Now, divide both sides by 15 to solve for x:

x = 105 / 15 x = 7

So, the solution for x in the second equation is x = 7.

3. 204 - x = 15

To solve for x in this equation, you need to isolate x on one side. Subtract 15 from both sides:

204 - 15 = x

x = 189

So, the solution for x in the third equation is x = 189.
