Answer 3

To solve these equations, we need to find the values of the variables 'x' and 'y'. Let's solve them one by one:

1. X - 5 × 6 = 25

To find the value of 'x', we'll first simplify the equation:

X - 30 = 25

Now, we'll isolate 'x' by adding 30 to both sides of the equation:

X = 25 + 30 X = 55

So, the value of 'x' is 55.

2. Y - 10 × 8 = 10

To find the value of 'y', we'll simplify the equation:

Y - 80 = 10

Now, isolate 'y' by adding 80 to both sides of the equation:

Y = 10 + 80 Y = 90

So, the value of 'y' is 90.

3. 23 × 7 - X = 20

To find the value of 'x', we'll first simplify the equation:

161 - X = 20

Now, isolate 'x' by subtracting 20 from both sides of the equation:

-X = 20 - 161 -X = -141

To solve for 'x', we multiply both sides by -1:

X = 141

So, the value of 'x' is 141.

To summarize: x = 55 y = 90 x = 141
