Answer:
Postulate.
Step-by-step explanation:
Postulate is a statement, also known as an axiom, which is taken to be true without proof.
3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
