Question

May someone please help with this Math problem. I tried doing some of It Myself. Thank you.

Answer 1

1.
-x + y = 3
>> -x + y + x = 3 + x
>> y = 3 + x


2.
3x - 2y = 5
>> 3x - 2(3 + x) = 5
>> 3x - 6 - 2x = 5
>> x - 6 = 5
>> x - 6 + 6 = 5 + 6
>> x = 11

3.
y = 3 + x
>> y = 3 + 11
>> y = 14

4.
x = 11, y = 14
Equation 1: -x + y = -11 + 14 = 3 (Correct)
Equation 1: 3x - 2y = 3(11) - 2(14) = 33 - 28 = 5 (Correct)
