Question

68*2-(x+90):4=7*8ypaвнeниe​

Answer 1

Ответ:

Х= 230

Пошаговое объяснение:

68*2-(x+90):4= 7*8=

136- (x+90):4= 56=

544-90= 454-x= 224=

454-224= 230

X=230

Answer 2

Ответ:

x=230

Пошаговое объяснение:

68*2-(x+90)/4=56

136-(x+90)/4=56

(x+90)/4=136-56

(x+90)/4=80

x+90=80*4

x+90=320

x=320-90

x=230

Answer 3

To solve the equation, let's simplify and isolate the variable "x":

68 * 2 - (x + 90) / 4 = 7 * 8

First, perform the multiplications:

136 - (x + 90) / 4 = 56

Now, subtract 136 from both sides to isolate the term with the variable:

-(x + 90) / 4 = 56 - 136

-(x + 90) / 4 = -80

To get rid of the fraction, multiply both sides by 4:

4 * (-(x + 90) / 4) = -80 * 4

This simplifies to:

-(x + 90) = -320

Now, to isolate "x," you can multiply both sides by -1 to change the sign:

x + 90 = 320

Now, subtract 90 from both sides to solve for "x":

x = 320 - 90

x = 230

So, the solution to the equation is x = 230.
