Question

Y=7-4x 6x=y+23 СПОЧНО!!!

Answer 1

Ответ:

6х=3х+23

23=6х-3х

3х=23

х=23÷3

х=7.6777

Answer 2

Ответ:

6х=у+23 ;у=7-4х

6х=7-4х+23

6х+4х=7+23

10х+30

х=3

Answer 3

To solve the system of equations:

Equation 1: Y = 7 - 4x

Equation 2: 6x = y + 23

We can substitute Equation 1 into Equation 2 to eliminate the variable y:

6x = (7 - 4x) + 23

Now, let's solve for x:

6x = 7 - 4x + 23

Combining like terms:

6x + 4x = 7 + 23

10x = 30

Divide both sides by 10:

x = 30/10

x = 3

Now, substitute the value of x back into Equation 1 to find y:

Y = 7 - 4(3)

Y = 7 - 12

Y = -5

Therefore, the solution to the system of equations is x = 3 and y = -5.
