(12, 1)

Answer 1

subtract 2nd equation from 1st equation.
tell me what u get.

Answer 2

\[\large{x-2y=14}\]
\[\large{x+3y=9}\]

solve for x in the first equation

Answer 3

it cant be a or d

Answer 4

x = 14+2y

now put this value in second one:
\[\large{(14+2y)+3y=9}\]

Answer 5

thats correct @Carol329
