Is (4,10) a solution to this system of equations?
y=2x+2
y=10x+1

1 answer

To determine if the point \((4, 10)\) is a solution to the system of equations, we need to check if it satisfies both equations:

  1. \( y = 2x + 2 \)
  2. \( y = 10x + 1 \)

First equation: Substitute \(x = 4\) and \(y = 10\) into the first equation:

\[ 10 = 2(4) + 2 \] \[ 10 = 8 + 2 \] \[ 10 = 10 \]

This equation is satisfied.

Second equation: Now substitute \(x = 4\) and \(y = 10\) into the second equation:

\[ 10 = 10(4) + 1 \] \[ 10 = 40 + 1 \] \[ 10 = 41 \]

This equation is not satisfied.

Since \((4, 10)\) satisfies the first equation but not the second one, we conclude that \((4, 10)\) is not a solution to the system of equations.
