Please Help! I will give you a lot of points and the brainiest if you do! --This is Hindu-Arabic math so you have to use this numbers system. The chart that says; 0, 1, 2, 3... and so on is what must be used to answer the question

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

x/3-10=8

x/3=18

x=48

i think that you should ask google for the answer to that problem because if we don't know it google does
