tentukan niliai x y dan z . 5y - 3y = 26 4y + 3z. = - 17 3x + 5z = -3

5y- 3y = 26 ...(1)
4y + 3z = -17 ...(2)
3x + 5z = -3 ...(3)

menemukan y

5y - 3y = 26
2y = 26
Y = 13

Subsitusi y= 13 ke (2)
4(13) + 3z = -17
52 + 3z = -17
3z = -69
Z = -23

Subsitusi z= -23 ke (3)
3x + 5(-23) = -3
3x - 115 = -3
3x = 112
X = 37 1/3

Semoga membantu
