Math Problem Statement

Is (-1, 5) a solution to the system of equations? 17x + 5y = 8 14x + 2y = -4

Solution

To determine if (1,5)(-1, 5) is a solution to the given system of equations, substitute x=1x = -1 and y=5y = 5 into each equation and verify if both equations are satisfied.

The system of equations is:

  1. 17x+5y=817x + 5y = 8
  2. 14x+2y=414x + 2y = -4

Step 1: Substitution into the first equation

Substitute x=1x = -1 and y=5y = 5 into 17x+5y=817x + 5y = 8: 17(1)+5(5)=817(-1) + 5(5) = 8 17+25=8-17 + 25 = 8 8=8(True!)8 = 8 \quad \text{(True!)}

Step 2: Substitution into the second equation

Substitute x=1x = -1 and y=5y = 5 into 14x+2y=414x + 2y = -4: 14(1)+2(5)=414(-1) + 2(5) = -4 14+10=4-14 + 10 = -4 4=4(True!)-4 = -4 \quad \text{(True!)}

Conclusion:

Since both equations are satisfied, (1,5)(-1, 5) is a solution to the system of equations. You should select "yes."
