Question

solve :x+y=5and x–y–1=0 by elimination method

Answer 1

Hey Friend ☺

☆ LINEAR EQUATIONS IN ONE VARIABLE ☆

x + y = 5. ... ( l )

x - y - 1 = 0

x - y = 1. ... ( 'll )

Adding equations ( l ) & ( 'll ) we get

x + y = 5
+
x - y = 1
_______
2x + 0 = 6

2x = 6

》 x = 6/2

》x = 3

Putting x = 3 in equation ( l ) we get

3 + y = 5

》y = 5 - 3

》y = 2

So x = 3 & y = 2

Hope it helps you ..!!

Answer 2

hello friend ,here is your answer ,

★★★first equation★★★
x+y=5

★★★secind equation★★★
x-y=1

___________________________

by applying elimination method .

x+y=5

x-y=1
_____

2x=6

——––

★★★★★★x=3 ★★★★★★

by putting value of x in the equation-1 to get ,

y+3=5

★★★★★★y=2★★★★★★
