The answer is the choice number C (5)

If the system has infinitely many solutions. Then the value of the coefficient of x will be 5.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Michael wrote the system of equations below, but he accidentally left out the coefficient of x in the first equation.

y = ax – 2

3y = 15x – 6

If the system has infinitely many solutions.

Then the value of a will be

The condition for infinitely many solutions will be

a₁ / a₂ = b₁ / b₂ = c₁ / c₂

Then we have

a / 15 = 1 / 3 = – 2/ (– 6)

a / 15 = 1 / 3 = 1 / 3

      a = 5

Thus, the correct option is C.
