Answer 2

1) 1000-х=35+6×8
1000-х=83
х=1000-83
х=923
1000-923=35+6×8
83=83
2) 81:у=63:7
81:у=9
у=81:9
у=9
81:9=63:7
9=9
3) х×8=100-(4×9)
х×8=64
х=64:8
х=8
8×8=100-(4×9)
64=64

Answer 3

Let's solve the equations step by step:

1. 1000 - x = 35 + 6 × 8

To find the value of x, we'll start by simplifying the right side of the equation:

35 + 6 × 8 = 35 + 48 = 83

Now the equation becomes:

1000 - x = 83

Next, let's isolate x by bringing it to one side of the equation:

x = 1000 - 83 x = 917

So, the value of x is 917.

2. 81:y = 63:7

To find the value of y, we'll use the cross-multiplication method:

81 × 7 = 567 63 × y = 63y

Now, set the two cross products equal to each other:

63y = 567

To isolate y, divide both sides by 63:

y = 567 / 63 y = 9

So, the value of y is 9.

3. x × 8 = 100 - (4 × 9)

First, let's calculate the value inside the parentheses:

4 × 9 = 36

Now the equation becomes:

x × 8 = 100 - 36

Now, let's simplify the right side of the equation:

100 - 36 = 64

The equation now becomes:

x × 8 = 64

To isolate x, divide both sides by 8:

x = 64 / 8 x = 8

So, the value of x is 8.

In summary:

• x = 917
• y = 9
• x = 8
