Question

Уравнение x:6=45-(18+12)

Answer 1

х=90

1/6х=45-(18+12)

1/6х= 45-30

1/6х= 15

х= 6*15

х=90

Answer 2

Пошаговое объяснение:

1) х : 6 = 45 - 30

2) х : 6 = 15

3) х = 15 : 6

4) х = 2,5

Answer 3

To solve the equation x:6=45-(18+12), we need to follow the order of operations (PEMDAS/BODMAS). This means we must first perform operations inside parentheses, then any exponents, followed by multiplication and division from left to right, and finally addition and subtraction from left to right.

Let's break it down step by step:

1. Simplify the expression inside the parentheses first: 18 + 12 = 30

2. Now we have: x:6 = 45 - 30

3. Subtract 30 from 45: 45 - 30 = 15

4. Finally, divide both sides of the equation by 6 to solve for x: x/6 = 15

To get x by itself, we need to undo the division by 6 by multiplying both sides by 6:

x = 15 * 6 x = 90

So, the solution to the equation is x = 90.
