Answer 2

To solve each of the equations, we need to find the value of "x" that makes the left-hand side of the equation equal to the right-hand side. Let's go through each equation step-by-step:

А) х = 4 This equation is already solved, and it means that x is equal to 4.

Б) х = 2 To solve the equation 8x + 9 - 6(3x + 2) = ?, we substitute x with the given value (x = 2) and simplify:

8(2) + 9 - 6(3(2) + 2) 16 + 9 - 6(6 + 2) 16 + 9 - 6(8) 16 + 9 - 48 25 - 48 -23

So, the solution is -23.

В) х = 5 3/11 To solve the equation 4(3x + 3) - 3(4x + 2) = ?, we substitute x with the given value (x = 5 3/11) and simplify:

4(3(5 3/11) + 3) - 3(4(5 3/11) + 2) 4(16/11 + 33/11) - 3(22/11 + 2) 4(49/11) - 3(24/11) 196/11 - 72/11 (196 - 72)/11 124/11

So, the solution is 124/11.

Г) х = -9 6/7 To solve the equation -9(2x - 8) + 2(9x - 10) = ?, we substitute x with the given value (x = -9 6/7) and simplify:

-9(2(-9 6/7) - 8) + 2(9(-9 6/7) - 10) -9(-23/7) + 2(-81/7 - 10) 207/7 - 2(81/7 + 10) 207/7 - 2(81/7 + 70/7) 207/7 - 2(151/7) 207/7 - 302/7 (207 - 302)/7 -95/7

So, the solution is -95/7.
