Answer 1

14(3x-15)=252
3x-15=252:14
3x-15=18
3x=18+15
3x=33
x=33:3
x=11

Answer 2

42х-210=252
42х=252+210
42х=462
х=462÷42
х=11

ОТВЕТ: 11

Answer 3

To solve the equation, you need to isolate the variable (in this case, x) on one side of the equation. Follow these steps:

Step 1: Distribute the number outside the parentheses. Step 2: Combine like terms. Step 3: Isolate the variable by performing inverse operations.

Let's go through the steps:

Step 1: Distribute the number outside the parentheses.

14(3x - 15) = 252

Expanding the left side:

42x - 210 = 252

Step 2: Combine like terms.

Now, let's get all the x terms on one side of the equation:

42x = 252 + 210

Step 3: Isolate the variable.

42x = 462

Now, to find the value of x, divide both sides by 42:

x = 462 / 42

x = 11

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