Answer:
Step-by-step explanation:
3*2x=6x, 3*5=10
So, 6x+10+4x = 5x+15
Add 6 and 4 which leaves you with 10x+10 = 5x+15
subtract 10 from 15 and that leaves you with 5 divided by 10x
x=2
Same for second equation
2*8x=16x and 2*3= 6
So 16x-6=16x+28
Add 6 to both sides so you get 34.
Now that 6 is gone you want x on one side so subtract 16x an it leaves you with 0. so X=34
A, the student failed to distribute. In his step one, he got 3x + 2 =y, but it's actually 3x + 6 = y
I got this by distributing 3 to both x and 2, which is 3x and 6.
Answer:
The original deposited amount in the bank is $3500.
Step-by-step explanation:
Here. Let us assume the principal amount deposited in bank = $P
The rate of interest = 8%
Total Amount in the bank after time period = $4340
Time Period = 3 yrs
Now, SIMPLE INTEREST 
⇒ SI = 
or Interest = 0.24 P
Now, AMOUNT = PRINCIPAL + INTEREST
⇒$4340 = P + 0.24 P
or, 4340 = 1.24 P
⇒ P = 1340 / 1.24 = 3500
Hence, the deposited amount in the bank for the duration of 3 years and interest rate 8% is $3500
When you estimate, make your numbers easy. I would round 2.12 to 2 and 58 to 60. then you would have 2 * 60 = 120 which would be close to 122.96
