Question

280÷7=X-18 3×X×10=300​

Answer 1

Пошаговое объяснение:

280÷7=X-18

х-18=40

х=58

3×X×10=300​

30х=300

х=10

Answer 2

Let's solve the equations step by step:

1. 280 ÷ 7 = X - 18

First, simplify the left side of the equation:

280 ÷ 7 = 40

So, the equation becomes:

40 = X - 18

Now, to solve for X, add 18 to both sides of the equation:

40 + 18 = X - 18 + 18

58 = X

So, X = 58.

2. 3 × X × 10 = 300

First, simplify the left side of the equation:

3 × X × 10 = 30X

Now, set the equation equal to 300:

30X = 300

To solve for X, divide both sides by 30:

(30X) ÷ 30 = 300 ÷ 30

X = 10

So, X = 10 in the second equation.

Therefore, the solutions are: X = 58 for the first equation. X = 10 for the second equation.
