Is (


4,5) a solution to this system of equations?
x=

4
y=
1
2
x+7

1 answer

To determine if the point \((-4, 5)\) is a solution to the system of equations given by:

  1. \( x = -4 \)
  2. \( y = \frac{1}{2}x + 7 \)

we can substitute \(x = -4\) and \(y = 5\) into the second equation and check if it holds true.

First, let's substitute \(x = -4\) into the second equation:

\[ y = \frac{1}{2}(-4) + 7 \]

Calculating this:

\[ y = -2 + 7 \] \[ y = 5 \]

Now, we see that when \(x = -4\), \(y\) does indeed equal \(5\). Therefore, the point \((-4, 5)\) satisfies both equations.

Thus, \((-4, 5)\) is a solution to the system of equations.
