Question

X×9=12×6, У+452=155×5, 63×У=63×3×0, 80×а=1000-6. решить уравнения

Answer 1

X×9=12×6
9х=72
х=72:9
х=8
У+452=155×5
у=775-452
у=323
63×У=63×3×0
63у=0
у=0
80×а=1000-6
80а=994
а=12,425

Answer 2

To solve the equations, we need to find the values of variables "X," "У," and "а" that satisfy each equation. Let's solve them one by one:

1. X × 9 = 12 × 6 To solve for X, we can start by dividing both sides of the equation by 9: X = (12 × 6) / 9 X = 72 / 9 X = 8

So, X = 8.

2. У + 452 = 155 × 5 To solve for У, we can start by subtracting 452 from both sides of the equation: У = 155 × 5 - 452 У = 775 - 452 У = 323

So, У = 323.

3. 63 × У = 63 × 3 × 0 We have 63 multiplied by У on the left side of the equation. We know that any number multiplied by 0 is equal to 0. So, У must be 0 to satisfy the equation.

So, У = 0.

4. 80 × а = 1000 - 6 To solve for а, we can start by subtracting 6 from both sides of the equation: 80 × а = 1000 - 6 80 × а = 994

Now, we can find the value of а by dividing both sides of the equation by 80: а = 994 / 80 а = 12.425

So, а ≈ 12.425.

To summarize: X = 8 У = 323 а ≈ 12.425
