Answer:
Multiply the second equation by -2
Step-by-step explanation:
Multiplying equation (II) by -2 makes it easy to continue the equation by elimination method.
the second equation becomes 3c -4d = 32.
Such that it becomes:
5c + 4d = 10... (I)
-6c -4d = -32... (III)
adding equation (1) and (III)
-c = -22
c = 22.
Hope its clear!?
