Answer:

To solve a system of of linear inequalities, you could do the elimination method or substitution method.

Explanation:

  • For elimination method, you can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

For substitution method, you have to:

Step 1 : First, solve one linear equation for y in terms of x.

Step 2 : Then substitute that expression for y in the other linear equation.

Step 3 : Solve this, and you have the x -coordinate of the intersection.

Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.
