Question

Jawabb secepatnyaa pleasee

Answer 1

A)
2y - x = 10
→ 2y = x + 10

3x + 2y = 29
3x + x + 10 = 29
4x = 29-10
x = 19/4
x = 4¾

2y = 19/4 + 10

y = 19/8 + 10/2

y = 2⅜ + 5

y = 7⅜

HP = { 4¾ , 7⅜ }


b)
x - 2y = 10
→ x = 2y + 10

3x + 2y = -2
3(2y + 10) + 2y = -2
6y + 2y = -2 - 30
y = -32/8
y = -4

x = 2(-4)+10
x = 2

hp = { 2 , -4 }
