Question

(53-х)+16=49 90+72:х=94

Answer 1

Ответ:

(53-x)= 49-16,

-x=33-53,

-x=-20,

X=20.

72:X=94-90

72:X=4,

4x=72,

X=72:4,

X=18

Answer 3

It looks like you've provided two equations with variables that you want to solve for. Let's solve them step by step:

Equation 1: (53 - x) + 16 = 49

First, let's simplify the left side of the equation by combining like terms:

53 - x + 16 = 49 69 - x = 49

Now, let's isolate the variable x by subtracting 69 from both sides of the equation:

-x = 49 - 69 -x = -20

Multiply both sides by -1 to solve for x:

x = 20

So, the solution for the first equation is x = 20.

Equation 2: 90 + 72 / x = 94

Let's isolate the variable x in this equation:

Subtract 90 from both sides of the equation:

72 / x = 94 - 90 72 / x = 4

Now, multiply both sides by x to solve for x:

x * (72 / x) = 4 * x 72 = 4x

Divide both sides by 4:

x = 72 / 4 x = 18

So, the solution for the second equation is x = 18.

To recap: Equation 1: x = 20 Equation 2: x = 18
