Answer:

  • (- 2, - 6)

Step-by-step explanation:

Given system:

  • x + 4y = -8
  • -1/4x + y = -1​

1. Multiply the second equation by - 4 to get:

  • (- 4)(-1/4x + y ) = (- 4)(- 1)
  • x - 4y = 4

2. Now, add this up with the first equation:

  • x + 4y + x - 4y = - 8 + 4
  • 2x = - 4
  • x = - 2

3. Find the value of y:

  • - 2 + y = - 8
  • y = - 8 + 2
  • y = - 6

The solution is (- 2, - 6)

  • Constant is a number that is not multiplied by any variable

Polynomials are algebraic expressions composed of variables, constants and exponents, that are combined using the mathematical operations such as addition, subtraction, and multiplication

Polynomials consists of variables and coefficients. The variables in polynomials are also called indeterminates. The coefficients also multiply this variables.

Thus, the parts of algebraic expressions related to polynomials are variables and coefficients.
