Question

the solution set of x+y-1=0 and 3x+3y - 2=0​

Answer 1

Step-by-step explanation:

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

3x +3y = 2 .....(2)

multiply (1) by 3

3x +3y = 3......(3)

This equation has no solutions......!!?

Answer 2

Solution 1:

=> x+y-1=0

=> 1 + 0 - 1 = 0 (X= 1: y= 0)

=> -1 + 2 - 1 = 0 (X= -1: y= 2)

=> -2 + 3 - 1 = 0 (X= -2: y= 3)

Solution 2:

=> 3x+3y - 2=0

=> 3x + 3y = 2

( In this equation, determining the value of X & y would result in decimals. Hence, it is not possible )
