Question

Решите систему уравнений a=6 2a-b=24 ответ: a=... b=...

Answer 1

Ответ:

a=6

b=12

Объяснение:

a=6

2*6-b=24

b=24-12

b=12

Answer 2

Ответ:

a=18; b=-12

Объяснение:

12-b=24

-b=12/(-1)

b=-12

2a - (-12)=24

2a=24+12

2a=36/2

a=18

Answer 3

To solve the system of equations, let's substitute the value of "a" from the first equation into the second equation and solve for "b."

Given:

1. a = 6
2. 2a - b = 24

Step 1: Substitute the value of "a" from the first equation into the second equation:

2(6) - b = 24

Step 2: Solve for "b":

12 - b = 24

Step 3: Move "b" to one side of the equation:

-b = 24 - 12 -b = 12

Step 4: Solve for "b" by multiplying both sides by -1:

b = -12

Now that we have found the value of "b," we can find the value of "a" by substituting it back into the first equation:

a = 6

So, the solution to the system of equations is:

a = 6 b = -12
