11. Check whetherr— 2, y = 1 is a solution of the following equations or not: (t) 2r-3y=1 (it) 5x-3Y+7=O (iil) 3x+5y-11-O IZ Find two solutions for each of the following equations

Answer»

Step-by-step explanation:

2r-3y=1 5x-3y+7=0 3X+5y-11=0

2r-3(1)=1 5x-3(1)+7=0 3x +5(1)-11=0

2r-3=1 5x-3+7=0 3x+5-11=0

2r=1+3 5x-3=-7 3x+5=11

2r=4 5x=-7+3 3x=11-5

r=4/-2 5x=-4 3x=6

r=-2 X =-4/5 x=6/-3

x=-2
