Question

find four solutions of the equation: 3x +5y=15.​

Answer 1

Answer:

3(3) + 5y = 15

9 + 5y = 15 Solution is (3,1)

5y = 6

y = 1

3x + 5(0)= 15

3x + 0 = 15 Solution is (5,0)

3x = 15

x = 5

3(0) + 5y = 15

5y = 15 Solution is (3,0)

y = 3

3x + 5(6) = 15

3x + 30 = 15 Solution is (6,-3)

3x = -15

x = -5
