Is (2,6) a solution to this system of equations?

y=
3
2
x+3
y=

9x+1

1 answer

To determine if the point (2, 6) is a solution to the given system of equations, we need to substitute \( x = 2 \) and \( y = 6 \) into each equation and check if both equations hold true.

  1. First Equation: \( y = \frac{3}{2}x + 3 \)

    Substitute \( x = 2 \):

    \[ y = \frac{3}{2}(2) + 3 \]

    \[ y = 3 + 3 = 6 \]

    So, the point (2, 6) satisfies the first equation.

  2. Second Equation: \( y = -9x + 1 \)

    Substitute \( x = 2 \):

    \[ y = -9(2) + 1 \]

    \[ y = -18 + 1 = -17 \]

    Here, \( y \) does not equal 6; it equals -17.

Since (2, 6) satisfies the first equation but not the second, it is not a solution to the system of equations.
