Simplifying the first equation:5 - 0.2y = 0-0.2y = -5y = 25
Simplifying the second equation:3y - 39 = 03(25) - 39 = 075 - 39 = 036 = 0
It seems like there is an error in the equations as we ended up with contradictory results in step 1 and step 2.
The simplified form of the third equation is -17 - 64a.
Simplifying the first equation:
5 - 0.2y = 0
-0.2y = -5
y = 25
Simplifying the second equation:
3y - 39 = 0
3(25) - 39 = 0
75 - 39 = 0
36 = 0
It seems like there is an error in the equations as we ended up with contradictory results in step 1 and step 2.
Simplifying the third equation:-21 + (4 - 10a) - 54a
-21 + 4 - 10a - 54a
-17 - 64a
The simplified form of the third equation is -17 - 64a.
