The sum of the digits in a two-digit number is 15. Three times the second digit equals two times the first digit. Write and solve a system of equations to represent this situation. Intepret the solution.

96 ordered pair form : (9, 6)

Step-by-step explanation:

x + y = 15

1x + 1y = 15

-1x

y = 15 - 1x (we did this so that it can be the in y=mx format)

3y = 2x (substitute the y for the solution above)

3 ( 15 - 1x ) = 2x

45 - 3x = 2x

+3x +3x

45 = 5x (divide 5 on both sides)

45/5 = 9 ; x = 9

now go back to the first equation and substitute the x for 9

y = 15 - 1(9)

y = 15 - 9

y = 6

hope this helped :)

b) well because you get well
