It is different because you are doing a different method to complete the problem. It is the same because it ends up with the same answer, provided you complete the process correctly.
Convert all fractions to have the same denominator.
To convert, we must find the least common multiple of the two denominators of the fractions:
Multiples of 4: {4,8,12,16,20}
Multiples of 5: {5,10,15,20}
The least common multiple of 4 and 5 is 20.
Multiply the fractions by a number that will result in the denominator being 20:


The equation should now look like this:

Subtract both sides by 8/20 to get w by itself:


The value of w is 7/20.
I really do wish I could help But I’m not sure I tried to figure it out and i just can’t get it
Answer:
45
Step-by-step explanation:
Together, these two angles form a flat line which is 180 degrees
(x + 7) + (4x - 52) = 180
5x - 45 = 180
+ 45 + 45
5x = 225
x = 45
C. 8^4x
64^2x = 4096x
8^4x= 4096x
