Math Problem Statement

What is the solution of the system of equations? Use the Substitution Method.

Solution

The image contains a system of linear equations with a solution being found using the substitution method. Let me transcribe and verify the solution provided.

System of equations:

  1. x=3y+16x = -3y + 16
  2. 2x+5y=142x + 5y = 14

Substitution method:

From the first equation, x=3y+16x = -3y + 16, substitute xx into the second equation.

2(3y+16)+5y=142(-3y + 16) + 5y = 14

Simplify: 6y+32+5y=14-6y + 32 + 5y = 14

Combine like terms: y+32=14-y + 32 = 14

Solve for yy: y=1432-y = 14 - 32 y=18-y = -18 y=18y = 18

Now substitute y=18y = 18 back into the first equation to find xx: x=3(18)+16x = -3(18) + 16 x=54+16x = -54 + 16 x=38x = -38

Solution:

The solution to the system of equations is: x=38,y=18x = -38, \, y = 18

Would you like a detailed explanation or help on another part of the question?
