Question

help me with answer please ​

Answer 1

Answer:

1 ) x = 5

2 ) M = 0

3) Y = -6

4) K = 40

5) r = 28

Answer 2

Answer:

1) x + 6 = 11

-- here, x = 5 as you can see,  6- 11 = 5.

2) M - 9 = -9

-- Here M variable's value is = 0 as you can see, -9 + 9 = 0

3) 4y + 3 = -21

--- Here, 4y = -6 * 4, so -6 is considered as the answer, there's a minus symbol as it's in a negative integer line.

4) k/5 = 8

-- As you can see, 5 / 8 = 40 , so k's value is 40.

5) r/ -4 = -7

-- As you can see, -4 / -7  = -28, so the r's value is -28

• 2nd main

Here the value of x is 4

And the value of y is -3

• How to find?

The triangle is an additive way. So in this case, the  number in the middle of the triangle is the sum of those three numbers in the vertices. So

10 + 2 + 8 = 20 an example

In the 2nd one there's an variable to find out -

5 + 2+ __ = 10

10 - 5 - 2 = 4

So the x value is 4

The next one you can see the numbers in the negative addition. So  to find out-

-10 + -2 + __ = -15

= -15 + 10 + 2 = -3

So the y value is -3
