Answer:
x = 5, y = -2.
Step-by-step explanation:
3x+2y=11
2x-2y=14
Adding removes the y terms:
5x = 25
x = 5.
Substitute for x in the first equation:
3(5) + 2y = 11
2y = 11 - 15 = -4
y = -2.
Answer:
[tex]3x + 2y = 11and2x - 2y = 14 \\ 2 \times 3x + 2 \times 2y = 2 \times 11and3 \times 2x + 3( - 2)y = 3 \times 12 \\ 6x + 4y = 22nd6x - 6y = 42 \\ 6x - 6x + 4y + 6y = 22 - 42 \\ 4y + 6y = 22 - 42 \\ 10y = 22 - 42 \\ 10y = - 20 \\ y = - 2 \\ \\ \\ \\ 2x - 2( - 2) = 14 \\ 2x + 4 = 14 \\ 2x = 10 \\ x = 5[/tex]
