unit 1 worksheet 5 solving systems of equations in 2 variables answer key

Answers

The solution to the system of equations is (3, -2).


What is system?

System is an organized set of components that interact to achieve a common goal. It is composed of elements that work together to achieve a larger purpose. Examples of systems include the human body, a solar system, an ecosystem, a computer system, and a political system. Each system has its own structure, components, and processes that work together to form a cohesive whole.

To solve for a system of equations in two variables, we use the substitution method.
First, we solve one equation for one of the variables. In this case, we solve the first equation for y:
y = -5x + 8
We then substitute this equation into the second equation and solve for x:
3x + (-5x + 8) = 4
3x - 5x = 4 - 8
-2x = -4
x = 2
Next, we substitute the value of x (2) into the equation we solved for y and solve for y:
y = -5(2) + 8
y = -10 + 8
y = -2
Therefore, the solution to the system of equations is (3, -2).
