Solve the simultaneous equation

x+2y=5
x²-y²=-3​

y = 14/3 and 2

x = -13/3 and 1

(-13/3, 14/3) and (1, 2)

Step-by-step explanation:

for equation (a)

make x the subject of the formular:

for equation (b)

substitute for x as 5 - 2y in equation (b):

therefore,

substitute for all values of y in equation (c):

for y = 14/3:

for y = 2:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
