Question

124:(у-5) =31(х-12) ×8 = 56​

Answer 1

Ответ:

1)124:(у-5)=31

у-5=124:31

у- 5=4

у=4+5

у=9

124:(9-5)=31

124:4=31

31=31

2)(х-12)×8=56

х-12=56:8

х-12=7

х=12+7

х=19

(19-12)×8=56

7×8=56

56=56

Answer 2

Ответ:

Пошаговое объяснение:

$124:(y-5)=31\\(y-5)=124:31\\(y-5)=4\\y=4+5\\y=9$

$(x-12)*8=56\\(x-12)=56:8\\(x-12)=7\\x=7+12\\x=19$

Answer 3

To solve the equation 124: (у-5) = 31(х-12) × 8 = 56, let's break it down step by step.

Step 1: Simplify the expression 31(х-12) × 8: 31(х-12) × 8 = 248(х-12)

Step 2: Substitute the expression back into the equation: 124: (у-5) = 248(х-12) = 56

Step 3: Simplify the left side of the equation: 124: (у-5) = 124/(у-5)

Step 4: Substitute the simplified left side back into the equation: 124/(у-5) = 248(х-12) = 56

Step 5: Set the expressions on both sides of the equation equal to each other: 124/(у-5) = 248(х-12) = 56

Now, we need more information or another equation to solve for the variables у and х. The given equation is not solvable as it stands.
