Answer:
x = 36
Step-by-step explanation:
Cross multiplication yields:
20x = 24(30), or
x = 24(30)/20 = 36
Answer:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Answer:
i would say B but i dont know
Step-by-step explanation:
Change both 4 to 2^2 and 8 to 2^3
you now have 2^2(4x-5)=2^3(3x-4)
2(4x-5)=3(3x-4)
8x-10=9x-12
x=2
