Answer:
x = 19.325
Step-by-step explanation:
You have: x - 4.225 = 15.1
Isolate x by adding 4.225 to both sides
x - 4.225 + 4.225 = 15.1 + 4.225
x = 15.1 + 4.225 = 19.325
x = 19.325

I'm too lazy to explain so here's a screen shot from desmos.
Answer
Together, they have 99 marbles.

Ravi has 33 marbles.
His brother has twice (two times) as many marbles as him. Ravi's brother has 33×2=66 marbles.
Together, they have 33+66=99 marbles.
Step-by-step explanation:
price difference= $45-$36
=$9
now,
x% of $45=$9
or, x/100 ×45 =9
or, x/20 ×9=9
or, x/20=1
therefore, x= 20%
