Algebra Problems

Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures.

Lets see some of the problems in algebra:

Example 1:Solve Graphically
x+y=-1; y-2x=-4


Answer: x+y=-1
y=-1-x
At x=-2, y=-1+2=1
At x=-3, y=-1+3=2
At x=0, y=-1-0=-1

y-2x=-4
y=2x-4
At x=1, y=2-4=-2
At x=-1, y=-2-4=-6
At x=0, y=0-4=-4
