Question

50-9*a=23 как решить это уравнение

Answer 1

-9а=23-50

-9а=-27

а=3

Answer 2

To solve the equation 50 - 9 * a = 23, follow these steps:

Step 1: Get the variable (a) on one side of the equation. Step 2: Isolate the variable (a) by performing necessary operations to both sides of the equation. Step 3: Solve for the value of the variable (a).

Let's proceed with the solution:

Step 1: We want to isolate the term containing 'a' on one side, so we'll move the constant term (23) to the other side.

50 - 9 * a = 23 Subtract 23 from both sides: 50 - 9 * a - 23 = 23 - 23 Simplify: 50 - 9 * a - 23 = 0

Step 2: Now, let's simplify the equation further:

27 - 9 * a = 0

Step 3: To isolate 'a,' we'll get rid of the constant term (27) by moving it to the other side. Since it is currently being subtracted from the left side, we'll add 27 to both sides:

27 - 9 * a + 27 = 0 + 27 Simplify: -9 * a + 27 = 27

Next, to solve for 'a,' we'll remove the constant term (27) from the left side. Since it is currently being added, we'll subtract 27 from both sides:

-9 * a + 27 - 27 = 27 - 27 Simplify: -9 * a = 0

Finally, to find the value of 'a,' we'll isolate 'a' by dividing both sides by -9:

(-9 * a) / -9 = 0 / -9 Simplify: a = 0

The solution to the equation is: a = 0
