-7x=21

x=-3

Answer 2

Ответ: а) 14*х-25=17 или х=(17+25)/14=3

Б) 12-7*х=51 или х=(12-51)/7=-39/7=-5 4/7.

Answer 3

To solve the equations, we will simplify and combine like terms, isolate the variable on one side, and solve for its value. Let's solve each equation step by step:

A) (12+5x) + (9x-37) = 176

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

12 + 5x + 9x - 37 = 176

Now, let's combine like terms:

14x - 25 = 176

Next, let's isolate the variable term by moving the constant term to the other side of the equation:

14x = 176 + 25

14x = 201

Finally, let's solve for x by dividing both sides of the equation by 14:

x = 201/14 x ≈ 14.36

B) (21+3x) - (10x-9) = 51

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

21 + 3x - 10x + 9 = 51

Combine like terms:

-7x + 30 = 51

Isolate the variable term:

-7x = 51 - 30

-7x = 21

Solve for x by dividing both sides by -7:

x = 21/(-7) x = -3

So, the solutions to the given equations are: A) x ≈ 14.36 B) x = -3
