To find the solution of the system of the two linear equations \( y = 4x - 10 \) and \( y = -2x + 8 \), we can set the two equations equal to each other since both are equal to \( y \):

\[ 4x - 10 = -2x + 8 \]

Now, we will solve for \( x \):

  1. Add \( 2x \) to both sides:

\[ 4x + 2x - 10 = 8 \]

This simplifies to:

\[ 6x - 10 = 8 \]

  1. Next, add \( 10 \) to both sides:

\[ 6x = 18 \]

  1. Now, divide both sides by \( 6 \):

\[ x = 3 \]

With \( x = 3 \), we can now substitute this back into either of the original equations to find \( y \). Let's use the second equation:

\[ y = -2(3) + 8 \]

Calculating gives:

\[ y = -6 + 8 = 2 \]

So the solution of the system is:

\[ (x, y) = (3, 2) \]

In summary, the solution to the system of equations is:

\[ \boxed{(3, 2)} \]
