X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
Answer:

Step-by-step explanation:
Given

Required
Express in standard form
To do this, we simply reorder the terms of the polynomial in descending order of power.
So, we have:

8160 dived by 85 equals 96, 2880 divided by 30 equals 96, therefore she can make 96 necklaces
Answer: Hence, the value of expression is 30 when p = 8.
Step-by-step explanation:
Since we have given that

and we have p = 8.
So, we substitute the value of p in the above expression.
so, it becomes,

Hence, the value of expression is 30 when p = 8.
