To find: the solution of the equation in the form of order pair and choose correct order pair form the options given below.

Answer to Problem 10CCSR
The option I is correct option.
Explanation of Solution
Given:
The options are:
Concept used:
The elimination method:
Either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites add the equations to eliminate a variable and when the coefficients of one variable are equal or subtract the equation to eliminate a variable.
Calculation:
The solution of the two equation can be solved using addition or elimination or substitution method.
Multiplying the equation
Taking elimination method by eliminating
Hence, option I is correct option.
