x = 9

Step-by-step explanation:

5x - 15 + 2x = 4x + 12

7x - 4x = 12 + 15

3x = 27

x = 9

Answer:

5\left(x-3\right)+2x=4\left(x+3\right)

5\left(x-3\right)+2x

=5x-15+2x

5x-15+2x

5x+2x-15=7x-15

4\left(x+3\right)=4x+12

7x-15=4x+12

7x-15+15=4x+12+15

7x=4x+27

7x-4x=4x+27-4x

3x=27

\frac{3x}{3}=\frac{27}{3}

x=9

Which statements are true about the ordered pair (2, 3) and the system of equations?
adoni [48]

Answer:

The Correct Answer are

  • The ordered pair (2, 3) is not a solution to the system of linear equations.
  • When (2, 3) is substituted into the first equation, the equation is true.
  • When (2, 3) is substituted into the second equation, the equation is false.​

Step-by-step explanation:

The Correct Answer are

  • When (2, 3) is substituted into the first equation, the equation is true.

3x + 4y = 18   equation ( 1 )

3×2 + 4×3 = 18

6 + 12 = 18

18  = 18

  • When (2, 3) is substituted into the second equation, the equation is false.​

2x – 2y = 2

2×2 - 2×3= 4 - 6 = -2≠2

  • The ordered pair (2, 3) is not a solution to the system of linear equations.

Solution means if we (2, 3) Substitute in both the Equation it Must Satisfy

But in Equation 1  it Satisfy

and in Equation 2 Not satisfy

Therefore It is NOT a solution to the system.
