tolong kak caranya gimana

2√x + 4√y = 10 ... pers 1
2√x - 3√y = 3 ... pers 2

#Eliminasi pers 1 dan 2
2√x + 4√y = 10
2√x - 3√y = 3
_____________ --
0 + 7√y = 7
√y = 7 / 7
√y = 1
(√y)² = (1)²
y = 1

#Subsitusi y = 1 ke pers 1
2√x + 4√y = 10
2√x + 4√(1) = 10
2√x + 4(1) = 10
2√x + 4 = 10
2√x = 10 - 4
2√x = 6
√x = 6/2
√x = 3
(√x)² = (3)²
x = 9


Maka nilai x = 9 dan y = 1 atau HP {9 , 1} In answer is opsi E
