Simplify. Combine like terms

7y - 3y = 4y

-12 + 9 = -3

----------------------------------------------------------------------------------------------------------------

4y - 3 = 0

Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.

4y - 3 (+3) = 0 (+3)

4y = 3

4y/4 = 3/4

y = 3/4

-----------------------------------------------------------------------------------------------------------------

y = 3/4 is your answer

-----------------------------------------------------------------------------------------------------------------

hope this helps

Consider the following two loans for P=$12,000.

Answer:

Simple interest-?

Step-by-step explanation:

P= 12000

T=5yrs

R=5%

Now,

Simple interest - PTR/100

= 12000*5*5/100

= $3000

Again,

P=12000

T=3yrs

R=8%

Now,

Simple interest - PTR/100

= 12000*3*8/100

= $2880

Hope this helps.
