I need help with these two equations

Ivan

for these you need to rearrange the equations and do substitutions.

#3 = if x+y=5 then you know x = 5-y

now substitute that equation for x in the 2nd one so x + 2y = 8 becomes

5-y + 2y = 8 2y - y becomes 1y which becomes y then subtract 5 from each side to get y =3

now replace y with 3 in the first equation x = 5-3 so x = 2

so (2,3) is the answer

same type of work for #4

2x-y=6 ,S0 y = 2X+6

so now you have 4x+2(2x+6)=-4

that becomes 4x +4x+12 = -4

8x+8 = 1, x =1

y = 2(1)-6 = -4

so answer is (1,-4)

What is the rate of interest on a loan of $2,000, for 284 days, if the amount of interest is $93.37, using the exact interest me

Viefleur [7K]

Answer: Option (c) is correct. Rate of interest = 6% p.a.

Step-by-step explanation:

Given that,

principal amount = $2000(loan)

time period = 284 days

interest amount (SI) = $93.37

we have to calculate the rate of interest (i),

Simple interest(SI) = principal amount × rate of interest (i) × time period

93.37 = 2000 × i × $\frac{284}{365}$

i = $\frac{34080.05}{568000}$

i = 0.06

i = 6%
