2(a-8)+7 = 5(a+2)-3a-19 Write original problem
2a-16+7 = 5a+10-3a-19 Use distribuitve property to multiply
the term in front of the parenthese
to the terms inside the parenthes.
2a-9=2a-9 Combine like terms
+9 +9 Add 9 on both sides
---------------
2a=2a + 0 Subtract 2a on both sides.
-2a -2a
--------------
0=0 Infinite amount of solutions

2(a-8)+7=5(a+2)-3a-19
2a-16+7 = 5a+10-3a-19
2a-5a+3a = 10-19+16-7
0 = 0
there seems to some mistake in writing down the equation

2(a-8)+7=5(a+2)-3a-19
2a-16+7=5a+10-3a-19
2a - 9 = 2a - 9
The expression on the left and the right are the same equation (or same line). So, if you plot these two together on the same xy-plane, these two lines are directlly on top of each other. Hence, there are infinitely many solutions.

2a - 16 + 7 = 5a + 10 - 3a - 19
2a - 9 = 2a - 9
Leading nowhere unfortunately.

The Left Hand SIde and The Right Hand side are the same.
For all values of a, that equation is as always fulfilled.

its infinitive number of solutions cuz after i do everything, it become 2a-9=2a-9

a can take any value and the equation will be valid
