Question

3 х + 3 = 18 - 2 х =

Answer 1

Сначала найдём х:
3х+3=18-2х,
5х=15,
х=3.
Значит (3*3+3=18-2*3)=(9+3)=(18-6)=12.
Ответ:12.

Answer 2

Let's solve for x step by step:

Given equation: 3x + 3 = 18 - 2x

First, let's simplify the equation by adding 2x to both sides: 3x + 2x + 3 = 18

Combining like terms on the left side: 5x + 3 = 18

Now, subtract 3 from both sides to isolate the variable term: 5x = 18 - 3 5x = 15

Finally, divide both sides by 5 to solve for x: x = 15 / 5 x = 3

So, the solution to the equation is x = 3.
