Use the elimination method to solve the system of equations choose the correct ordered pair x-y=2 2x+3y =14
a.(4,2)
b.(5,3)
c.(6,4)
d.(3,1)

Option A is correct

Step-by-step explanation:

Given two equations

we have to solve the above equations using elimination method.

Multiplying (1) equation by 2, we get

Subtract equation (3) from (2), we get

Dividing by 5, we get

(1) implies x-y=2

hence, the solution is (4,2)

Option A is correct.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

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
