## How many solutions does a linear inequality have?

Therefore, the solution set of a single linear inequality is always a half plane, so there are infinitely many solutions. So, for a linear inequality in two variables, there are infinitely many numbers of solutions.

### How many solutions does a linear equation have in two variables explain?

For linear equations in two variables, there are infinitely many solutions.

**What is the solution to a linear inequality?**

The solution to a system of linear inequality is the region where the graphs of all linear inequalities in the system overlap.

**How do you find the solution to a linear inequality?**

- Step 1: Solve the inequality for y.
- Step 2: Graph the boundary line for the inequality.
- Step 3: Shade the region that satisfies the inequality.
- Step 4: Solve the second inequality for y.
- Step 5: Graph the boundary line for the second inequality.
- Step 6: Shade the region that satisfies the second inequality.

## Can a linear equation have 3 variables?

(The “three variables” are the x, the y, and the z.) The numbers a, b, and c are called the coefficients of the equation. 3x + 4y – 7z = 2, -2x + y – z = -6, x – 17z = 4, 4y = 0, and x + y + z = 2 are all linear equations in three variables.

### What is the degree of linear inequality?

Linear inequalities are also called first degree inequalities, as the highest power of the variable (or pronumeral) in these inequalities is 1. E.g. 4x > 20 is an inequality of the first degree, which is often called a linear inequality. For example, the linear equation 6x = 24 is a true statement only when x = 4.

**How Do You Solve 3 linear equations with 2 variables?**

Pick any two pairs of equations from the system. Eliminate the same variable from each pair using the Addition/Subtraction method. Solve the system of the two new equations using the Addition/Subtraction method. Substitute the solution back into one of the original equations and solve for the third variable.

**How do you do linear inequalities?**

There are three steps:

- Rearrange the equation so “y” is on the left and everything else on the right.
- Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).
