Math Problem Statement

Solve the system of equations: 3x + 5y = 2 and x + 4y = -4.

Solution

The image shows a set of algebraic equations along with corresponding steps on the right-hand side labeled with actions like "Multiplication prop," "Addition prop," and others.

Let me go through the parts:

Left Column (Labeled S):

  1. 3x+5y=23x + 5y = 2
  2. x+4y=4x + 4y = -4
  3. 1(3x+5y)=(2)(1)-1(3x + 5y) = (2)(-1)
  4. 3(x+4y)=(4)(3)3(x + 4y) = (-4)(3)
  5. 3x+5y=2-3x + -5y = -2
  6. 3x+12y=123x + 12y = -12
  7. 3x+12y=14-3x + 12y = -14
  8. y=2y = -2
  9. 3x+5(2)=23x + 5(-2) = 2
  10. 3x10=23x - 10 = 2

Right Column (Labeled R):

  1. Given
  2. Given
  3. Multiplication prop (property)
  4. Multiplication prop
  5. Distributive prop
  6. Distributive prop
  7. Elimination
  8. Substitution
  9. Division prop
  10. Multiplication prop
  11. Addition prop
  12. Division prop

It seems this is part of solving a system of linear equations using substitution or elimination. The steps involve manipulating the two equations, applying properties of equality like distribution, multiplication, and substitution, to find the value of yy and xx.

If you'd like, I can help verify each step, or go through the solution in more detail.

Would you like further explanation of specific parts?

Questions:

  1. Would you like help solving for xx after y=2y = -2?
  2. Should we break down the properties (like multiplication and substitution) step by step?
  3. Are you familiar with how elimination is used to solve systems of equations?
  4. Would you like a more detailed explanation of how substitution was applied?
  5. Would you like to check if the system has a unique solution, or if it's consistent?

Tip:

When solving systems of equations, elimination works well when the goal is to cancel out one variable by adding or subtracting the equations.
