StartFraction 3 (6) minus 1 Over 2 (6) + 1 EndFraction
StartFraction (6) Over 2 (6) + 1 EndFraction
StartFraction 36 minus 1 Over 26 + 1 EndFraction
StartFraction (6) minus 1 Over (6) + 1 EndFraction

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
