Question

Find the four solutions. y=3x​

Answer 1

Answer:

f(x) = y = 3x

So,

1) When y = 1,

1 = 3x

=> x = 1/3

2) When y = 2,

2 = 3x

=> x = 2/3

3) When y = 3,

3 = 3x

=> x = 1

4) And, when y = 4,

4 = 3x

=> x = 4/3

Thus, four solution of given equation are:

y = 1, x = 1/3

y = 2, x = 2/3

y = 3, x = 1

y = 4, x = 4/3

Answer 2

f(x) = y = 3x

So,

1) When y = 1,

1 = 3x

=> x = 1/3

2) When y = 2,

2 = 3x

=> x = 2/3

3) When y = 3,

3 = 3x

=> x = 1

4) And, when y = 4,

4 = 3x

=> x = 4/3

Thus, four solution of given equation are:

y = 1, x = 1/3

y = 1, x = 1/3y = 2, x = 2/3

y = 1, x = 1/3y = 2, x = 2/3y = 3, x = 1

y = 1, x = 1/3y = 2, x = 2/3y = 3, x = 1y = 4, x = 4/3
