gunakan metode eliminasi 5y+2x-15=0dan3y-2x-13=0

• 5y + 2x - 15 = 0
5y + 2x = 15
• 3y - 2x - 13 = 0
3y - 2x = 13


Eliminasi
5y + 2x = 15
3y - 2x = 13
__________ +
8y = 28
y = 28/8
y = 3,5

Untuk mencari nilai x, gunakan metode substitusi
3y - 2x = 13
3(3,5) - 2x = 13
10,5 - 2x = 13
-2x = 13 - 10,5
-2x = 2,5
x = 2,5/-2
x = -1,25
