6x+3y=54 2x+y=18 system of equation using substitution

, where R stands for all real numbers.

Step-by-step explanation:

Part 1: Solving one equation for its variable

First, we need to solve one of the equations for one of its variables. I will use the second equation.

  Subtract from both sides to isolate the .

Part 2: Substituting the solved variable value into the other equation

Now, simply substitute this value in the place of the in the first equation and solve for .

   Distribute the coefficient of the equation.

   Simplify the equation.

This answer is perfectly okay to get. This means that your equations have an infinite number of solutions.
