1)5х+(3×-3)=6×+112)(×+7)-(2×+9)=-13​

Answer 1

Ответ:

Пошаговое объяснение:

1)

5х+(3x-3)=6x+11

5x + 3x - 3 = 6x + 11

8x - 3 = 6x + 11

8x - 6x = 11 + 3

2x = 14

x = 14 : 2

x = 7

2)

(x+7)-(2x+9)=-13​

x + 7 - 2x - 9 = -13

-x - 2 = -13

x = 13 - 2

x = 11

Answer 2

To solve the equations you provided:

1. 5x + (3x - 3) = 6x + 11

First, let's simplify the equation by removing the parentheses:

5x + 3x - 3 = 6x + 11

Combining like terms:

8x - 3 = 6x + 11

Next, let's isolate the variable terms on one side and the constant terms on the other side:

8x - 6x = 11 + 3

2x = 14

Finally, solve for x by dividing both sides of the equation by 2:

x = 14/2

x = 7

Therefore, the solution to the equation is x = 7.

2. (x + 7) - (2x + 9) = -13

Let's simplify the equation by removing the parentheses:

x + 7 - 2x - 9 = -13

Combining like terms:

-x - 2 = -13

Next, let's isolate the variable term on one side and the constant term on the other side:

-x = -13 + 2

-x = -11

Finally, solve for x by multiplying both sides of the equation by -1 (to change the sign):

x = (-11) * (-1)

x = 11

Therefore, the solution to the equation is x = 11.
