What is the solution for the system of equations?

y=2x−3

4x−3y=31

(2 points)
The solution to the system is (___)(____)

1 answer

To solve the system of equations, we can substitute the expression for \( y \) from the first equation into the second equation. The two equations are:

  1. \( y = 2x - 3 \)
  2. \( 4x - 3y = 31 \)

Substituting the first equation into the second:

\[ 4x - 3(2x - 3) = 31 \]

Now, simplify the equation:

\[ 4x - 6x + 9 = 31 \]

Combine like terms:

\[ -2x + 9 = 31 \]

Subtract 9 from both sides:

\[ -2x = 22 \]

Now, divide by -2:

\[ x = -11 \]

Now, substitute \( x = -11 \) back into the first equation to find \( y \):

\[ y = 2(-11) - 3 \] \[ y = -22 - 3 \] \[ y = -25 \]

Therefore, the solution to the system of equations is:

\[ (x, y) = (-11, -25) \]

So, the final answer is:

The solution to the system is (−11)(−25).
