First, combine like terms.
12y+6=6y+12 turns into
12y-6y=12-6, which is
6y=6. Now divide both sides by 6.
y=1
now do a quick check (cause that's always a good idea).
12(1)+6=6(1)+12
12+6=6+12
18=18 ; )
Answer:
x = 0, y = -3
Step-by-step explanation:
plug in x as y + 3 into the first equation
6(y+3) - 5y = 15
6y+18 - 5y = 15
y = -3
x= 0
Answer:
x = 2
/3 = 1.500
Step-by-step explanation:
If the interest is $90 from $750 loan amount, we can calculate the periodic (4 weeks) interest rate of the loan using the below formula.
*interest amount / loan amount x 100 = periodic interest rate of loan*
To integrate the values, we have:
$90 / $750 = 0.12 multiplied to 100 will result to 12.
Therefore, the periodic interest rate of loan is 12% or $90 is 12% from loan amount of $750.
