40+x:70=54 142-(123-х)+14=11167 - 36:х=55решите пожалуйстарешение и ответ

Answer 1

40+х÷70=54
х÷70=54-40
х÷70=14
х=14×70
х=980

142-(123-х)+14=111
-(123-х)=111-142-14
-(123-х)= -45
-123+х= -45
х= -45+123
х=78

67-36÷х=55
36÷х=67-55
36÷х=12
х=36÷12
х=3

Answer 2

To solve the equations, let's take them one by one:

1. 40 + x : 70 = 54

To solve for x, we first need to isolate x on one side of the equation. We'll do that step by step:

Step 1: Subtract 40 from both sides. x / 70 = 14

Step 2: To isolate x, we'll multiply both sides by 70. x = 14 * 70 x = 980

So the solution for x is x = 980.

2. 142 - (123 - x) + 14 = 11167

Step 1: Solve the expression inside the parentheses. 142 - (123 - x) + 14 = 142 - 123 + x + 14 = 33 + x

Step 2: Simplify the equation. 33 + x = 11167

Step 3: Now, isolate x by subtracting 33 from both sides. x = 11167 - 33 x = 11134

So the solution for x is x = 11134.

3. -36 / x = 55

Step 1: To isolate x, multiply both sides by x. -36 = 55 * x

Step 2: Divide both sides by 55 to solve for x. x = -36 / 55

The solution for x is x = -36 / 55.

Please note that for the third equation, "55решите" is not clear in terms of its meaning, so I have assumed it refers to solving for x as per the context. If you have any specific questions or clarifications, feel free to ask!
