Question

1000-х=35+6*8 81:у=63:7 Х*8=100-(4*9)

Answer 1

1000-х=35+6*8

1000-x = 35+48

1000-x = 83

x = 1000 - 83

x = 917

81:у=63:7

81:y=9

y=81:9

y=9

Х*8=100-(4*9)

x*8=100-36

8x=64

x=64:8

x=8

Answer 2

Let's solve the equations step by step:

1. 1000 - x = 35 + 6 * 8

First, perform the operations on the right side of the equation: 35 + 6 * 8 = 35 + 48 = 83

Now, the equation becomes: 1000 - x = 83

Next, isolate x by moving 1000 to the other side: x = 1000 - 83 x = 917

So the value of x is 917.

2. 81 / y = 63 / 7

Cross-multiply to solve for y: 81 * 7 = 63 * y

Now, divide both sides by 63 to find y: y = (81 * 7) / 63 y = 567 / 63 y = 9

So the value of y is 9.

3. x * 8 = 100 - (4 * 9)

Perform the operations on the right side of the equation: x * 8 = 100 - (4 * 9) = 100 - 36 = 64

Now, isolate x by dividing both sides by 8: x = 64 / 8 x = 8

So the value of x is 8.

To summarize: x = 917 y = 9 x = 8
