Question

A/3 + b/2 - c = 7
a/4 - 3b/2 + c/2 = -6
a/6 - b/4 - c/3 = 1

berapakah nilai a,b,c? dengan caranya ya! thnks

Answer 1

A/3 + b/2 - c = 7 ---> kalikan 6
2a + 3b - 6c = 42......(1)

a/4 - 3b/2 + c/2 = -6 ...kalikan 4
a -  6b + 2c = - 24.....(2)

a/6 - b/4 - c/3 = 1 ....kalikan 12
2a - 3b - 4c = 12......(3)

eliminasikan ketiga persamaan nya
