Lesson 8: systems of equations and inequalities unit test ce 2015
algebra 1 unit 7: systems of equations and inequalities

We are asked to find which graph represents the solution of the given system of equations:

and

We find the intersection point of the two equations by solving these system of equations using elimination method as:

subtract equation (2) from equation (1) to obtain:

Also putting this value of x in equation (1) we get:

Hence, the intersection point is:  (0.75,1.25).

Hence the graph that represents the solution of the system of given linear equations is attached to the answer.

answer is : muchas/tipicas

have a nice day!

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
