[(y+4)/(y+7)]+1=(y+3)/(y+1)

Sunny_sXe [5.5K]

<span>First note that y cannot equal -7 or -1 as division by zero is undefined. So that if it comes up in our solution we know that it is not a real solution.

[(y+4)/(y+7)]+1=(y+3)/(y+1) make the left side have a common denominator

(y+4+y+7)/(y+7)=(y+3)/(y+1) combine like terms on left side

(2y+11)/(y+7)=(y+3)/(y+1) cross multiply

(2y+11)(y+1)=(y+3)(y+7) expand

2y^2+13y+11=y^2+10y+21 subtract y^2 from both sides

y^2+13y+11=10y+21 subtract 10y from both sides

y^2+3y+11=21 subtract 21 from both sides

y^2+3y-10=0 expand so factoring is easier

y^2-2y+5y-10=0 factor

y(y-2)+5(y-2)=0 which is equal to

(y+5)(y-2)=0

y=-5 or 2</span>

anna has 300naira and ojo has 1860naira.if anna saves 50 naira a day and ojo spends 70 a day, after how many days will they have

ExtremeBDS [4]

Answer:

Anna and Ojo will have same amount after 13 days.

Step-by-step explanation:

Given that:

Anna has 300 naira

She saves 50 naira per day.

Let,

x be the number of days.

y be the amount saved

y = 50x + 300

Ojo has 1860 naira

He spends 70 naira per day.

Let,

x be the number of days

y be the amount left

y = 1860 - 70x

For equal amount, the equations will be equal

50x +300 = 1860 - 70x

50x + 70x = 1860 - 300

120x = 1560

Dividing both sides by 120

$\frac{120x}{120}=\frac{1560}{120}\\x=13$

Hence,

Anna and Ojo will have same amount after 13 days.
