Question

А)(х-87)-27=36 б)87-(41+у)=22

Answer 1

а) (х-87)-27=36

х-87-27=36

х=36+87+27

х=150

х=150:1

х=150

 

б)87-(41+у)=22

87-41-у=22

-у=22+87+41

-у=150

-у=150(-1)

-у=-150

Answer 2

а) (х-87)-27=36

     х-87=36+27

     х-87=63

     х=63+87

     х=150

 (150-87)-27=36

 

б) 87-(41+у)=22

     41+у=87-22

     41+у=65

       у= 65-41

      у=24

   87-(41+24)=22

Answer 3

Equation A: (х-87)-27=36

To solve this equation, we can follow these steps:

Step 1: Simplify the equation by combining like terms on both sides.

Let's start by simplifying the left side of the equation: (x - 87) - 27

To remove the parentheses, we distribute the negative sign to each term inside the parentheses: x - 87 - 27

Now, we can combine the like terms on the left side: x - 114

The equation becomes: x - 114 = 36

Step 2: Isolate the variable on one side of the equation.

To isolate the variable x, we need to get rid of the constant term on the left side. We can do this by adding 114 to both sides of the equation: x - 114 + 114 = 36 + 114

Simplifying the equation further: x = 150

So, the solution to equation A is x = 150.

Equation B: 87 - (41 + у) = 22

To solve this equation, we can follow these steps:

Step 1: Simplify the equation by combining like terms on both sides.

Let's start by simplifying the right side of the equation: 87 - (41 + у)

To remove the parentheses, we distribute the negative sign to each term inside the parentheses: 87 - 41 - у

Now, we can combine the like terms on the right side: 46 - у

The equation becomes: 46 - у = 22

Step 2: Isolate the variable on one side of the equation.

To isolate the variable у, we need to get rid of the constant term on the right side. We can do this by subtracting 46 from both sides of the equation: 46 - у - 46 = 22 - 46

Simplifying the equation further: -у = -24

Step 3: Solve for the variable.

To solve for у, we need to isolate the variable by multiplying both sides of the equation by -1: -1 * (-у) = -1 * (-24)

Simplifying further: у = 24

So, the solution to equation B is у = 24.

Therefore, the solutions to the given equations are: A) x = 150 B) у = 24
