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:

both equations and proportions are better.
