Find the solution to the system of equations. Write the solution as an ordered pair.

3x – 2y = –9
4x + 3y = 22

Step-by-step explanation:

3x - 2y = –9

3x−2y+2y=−9+2y

3x=2y−9/3x^3

=2y−9/3

x=2/3y−3

4x + 3y = 22

4x+3y+−3y=22+−3y

4x=−3y+22

4x4

=−3y+22/4

x=−3/4y+11/2

because that’s us why

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
