Can you show your workings as i really don’t get this

The solutions are x = 3, y=10  and x=7, y=30.

Step-by-step explanation:

We use substitution to solve this:

5x - y = 5

y = 5x - 5

Now substitute for y in the  second equation:

2y - x^2 = 11        Replace y by 5x - 5:-

2(5x - 5) - x^2 = 11

10x - 10 - x^2 = 11

x^2 - 10x + 21 = 0

(x - 3)(x - 7) = 0

x = 3 , 7.

Now we find the values of y corresponding to these 2 values of x:

When x = 3 ( using y = 5x - 5):

y = 5*3-5 = 10 and

when x = 7

y = 5*7 - 5 = 30.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
