Question

How many solutions does it have ?

Y =4
Y =4x-1

Answer 1

To find the solutions for this system of equations, we can substitute the value of y from the first equation into the second equation and solve for x. That is:

4 = 4x - 1

Adding 1 to both sides, we get:

5 = 4x

Dividing both sides by 4, we get:

x = 5/4

Therefore, the system has a unique solution, which is (x, y) = (5/4, 4).

Answer 2

1 solution

Explanation:

Y = 4

Y = 4x - 1

Substitute value of Y here,

4 = 4x - 1

4 + 1 = 4x

5 = 4x

5/4 = x

1.25 = x

•°• The given equation can have only 1 solution, i.e, a linear equation with 1 variable gives only 1 solution.
