6j-k=233k+6j=11Solve j and k using the elimination method on the simultaneous equations
1 answer:
Answer:
Step-by-step explanation:
6j - k = 23
6j + 3k = 11.....multiply by -1
---------------
6j - k = 23
-6j - 3k = -11 (result of multiplying by -1)
---------------
-4k = 12
k = -12/4
k = - 3 <=====
6j - k = 23
6j - (-3) = 23
6j + 3 = 23
6j = 23 - 3
6j = 20
j = 20/6
j = 10/3 <===
solution is : j = 10/3 and k = -3
