Question

-7/15x - 3 = 1 2/3срочно ​

Answer 1

Ответ:

-7/15х - 3 = 1 2/3

-7/15х= 1 2/3 +3

-7/15х= 4 2/3

х= -7/15 : 4 2/3

-7/15 : 4 2/3 = -7/15 * 3/14 = -1/10.

х= -1/10

Это если дробь 1 2/3 подразумевалась как одна целая две третьих.

Answer 2

To solve the equation (-7/15)x - 3 = 1 2/3, follow these steps:

Step 1: Convert the mixed number 1 2/3 to an improper fraction. 1 2/3 = (1 * 3 + 2) / 3 = 5 / 3

Step 2: Rewrite the equation with the improper fraction. (-7/15)x - 3 = 5/3

Step 3: Isolate the term with x on one side of the equation. To do this, move the constant term (-3) to the other side by adding 3 to both sides of the equation. (-7/15)x = 5/3 + 3

Step 4: Convert the constant term on the right side to a fraction with a common denominator. 5/3 + 3 = 5/3 + 9/3 = (5 + 9) / 3 = 14 / 3

Step 5: The equation now becomes: (-7/15)x = 14/3

Step 6: To solve for x, multiply both sides of the equation by the reciprocal of (-7/15), which is -15/7. x = (14/3) * (-15/7)

Step 7: Perform the multiplication on the right side of the equation. x = -210/21

Step 8: Simplify the fraction, if possible. x = -10

So, the solution to the equation is x = -10.
