<span>A system of linear inequalities is two or more linear inequalities. The solution of a system of linear inequalities is the region of the plane where each of the individual inequalities is true. To find this, graph the inequalities. The solution to the system is the region where the graphs of all of the inequalities overlap. (The solution to a linear inequality is generally a half-plane. If you have > or < the boundary is a dotted line to indicate that the line itself is not included in the solution set. If you have ≥ or ≤ the boundary is a solid line to indicate that the line is included in the solution set.)</span>
Minus
The quadratic equation is
( -b+-SQRT(b^2 - 4ac) )/2a
Graph 1 is y = 4.
You can tell this because no matter what point you pick on that line, the ordered pair will contain the number 4 for y. You can also tell because y = a number graphs are always horizontal lines.

= 8
First, simplify

to 3. / Your problem should look like: v + 3 = 8.
Second, subtract 3 from both sides. / Your problem should look like: v = 8 - 3.
Third, simplify 8 - 3 to 5. / Your problem should look like: v = 5, which is your answer.
