Answer:
Step-by-step explanation:
X/7=3/2 multiply by : 5
x = 21/2
Answer:
Step-by-step explanation:
Let
be the greater number and
be the smaller number. We know that their difference is 15, so we have

Then, we have the following information: if we add twice the greater (2x) and 8 (2x+8), the result is 3 times the lesser (3y) minus four (3y-4). So, we have

So, we have the follwing system:

From the first equation, we can derive
, and substitute this expression in the second equation to get

Substitute this value for y in the first equation to get

Answer:
36 and 27
Step-by-step explanation:
4+3=7
63/7=9
9x4=36
9x3=27
