Question

А+85, а×18. а=8 как решить

Answer 1

Если а=8, то 8+85=93

Если а=8, то 8×18=144

Answer 2

To solve the given equations, we need to find the values of "а" that satisfy both of them simultaneously. Let's start by solving each equation step by step:

1. Equation: "а + 85 = 8" To find the value of "а," we can isolate "а" on one side of the equation. To do that, we'll subtract 85 from both sides:

а + 85 - 85 = 8 - 85 а = -77

So, the solution to the first equation is "а = -77."

2. Equation: "а × 18 = 8" Now we'll solve the second equation for "а." To find the value of "а," we need to divide both sides by 18:

(а × 18) ÷ 18 = 8 ÷ 18 а = 8 ÷ 18 а = 4/9

So, the solution to the second equation is "а = 4/9."

Now, we need to check if there is a common value of "а" that satisfies both equations:

Since "а = -77" from the first equation, we can check if it satisfies the second equation:

(-77) × 18 = -1386 ≠ 8

Since "а = 4/9" from the second equation, we can check if it satisfies the first equation:

(4/9) + 85 = 85⅓ ≠ 8

It turns out that there is no value of "а" that satisfies both equations simultaneously. The system of equations is inconsistent, and there is no solution that satisfies both "а + 85 = 8" and "а × 18 = 8" at the same time.

Answer 3

To solve the given equations, follow these steps:

1. Replace "а" with 8 in the equations:

   A + 85 = 8 A × 18 = 8

2. Solve for A in the first equation:

   A = 8 - 85 A = -77

3. Substitute the value of A in the second equation:

   (-77) × 18 = -1386

So the solution for the given equations is A = -77.
