Which part do you need help on?
Answer:
579o
Step-by-step explanation:
61+ 62=123o
180-123= 57
J = 57o
Place value of 4 is 4/100
Multiply -3[4x+y=6].
This gets you -12x-3y=-18.
Add the two equations together to eliminate the y.
-12x - 3y = -18
+ 12x + 3y = 18
------------------------
0 = 0
This means that these are in fact the same line, therefore there are infinite solutions.
