Question

2x+3y=2;x-y/2=1/2
2x+3y=2---------(1)

x-y/2=1/2

=>(2x-y)/2=1/2

=>2x-y=2/2

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

or,

2x=1+y

x=(1+y)/2

putting the value of x in eqn(1):-

2{(1+y)/2}+3y=2

=>1+y+3y=2

=>1+4y=2

=>4y=2-1

=>4y=1

=>y=1/4

putting the value of y in eq(1):-

2x+3y=2

=>2x+3(1/4)=2

=>2x+3/4=2

=>2x=2-3/4

=>2x=(8-3)/4

=>2x=5/4

=>x=5/8

hence,x=5/8 and y=1/4​

Answer 1

Step-by-step explanation:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.Original cost of motorcycle. Cost decreased = 22% = 40,000

New cost = = 100% -22% of 40,000 78% of 40000

= 78 X 40000

100.

78 x 400

31200
