Answer 2

Ответ:

m=2

Объяснение:

(28m – 36): (14m – 18) - (3(11m - 14) - 7(8m – 12)) = 6.

​2-(33m-42-56m+84)= 6

2+23m-42=6

23m=46

m=46^23

m=2

Answer 3

Let's solve the equation step by step:

Given equation: (28m – 36) - (14m – 18) - (3(11m - 14) - 7(8m – 12)) = 6

First, let's simplify the expressions within the parentheses:

28m – 36 = 28m - 36 14m – 18 = 14m - 18 3(11m - 14) = 33m - 42 7(8m – 12) = 56m - 84

Now substitute these simplified expressions back into the equation:

(28m - 36) - (14m - 18) - (33m - 42 - 56m + 84) = 6

Distribute the negative sign in the third term:

28m - 36 - 14m + 18 - 33m + 42 + 56m - 84 = 6

Combine like terms:

(28m - 14m - 33m + 56m) + (-36 + 18 + 42 - 84) = 6

37m - 60 = 6

Add 60 to both sides of the equation:

37m = 66

Finally, divide both sides by 37:

m = 66 / 37

This is the simplified value of 'm'. If you need a decimal approximation, you can calculate it:

m ≈ 1.78378378378

So, the solution for the given equation is approximately m = 1.784.
