Question

Solve each of the following system of equations by elimination method.

Answer 1

Here is your answer :-

x + 2y = 7 ......(1)

x - 2y = 1.........(2)

Add both the equations,

2x = 8
x = 4

Now,
Put the value of x in eq (1).

➡ x + 2y = 7

➡ 4 + 2y = 7

➡ 2y = 3

➡ y = 3/2

Answer :-
x = 4 and y = 3/2

Hope it will help you !!!

Answer 2

Hiii friend !!!



X + 2Y = 7 ------(1)


X -2Y = 1 --------(2)




Using elimination method :-


Adding equation (1) and (2) we get,



X + 2Y = 7

X - 2Y = 1
----------------


2X = 8

X = 8/2

X = 4


Putting X = 4 in equation (1)


X + 2Y = 7

4 + 2Y = 7

2Y = 7-4

Y = 3/2



Hence,


X = 4 and Y = 3/2
