DE + EF = DF
x - 2 + 6x + 4 = 8x - 2
7x + 2 = 8x - 2
2 + 2 = 8x - 7x
4 = x <===
Answer:
A) 5x + 2y = 22
B) -2x + 6y = 3 We'll multiply A) by -3
A) -15x -6y = -66 Then we'll add B)
B) -2x + 6y = 3
-17x = -63
x = 3.7058823529
y = 1.7352941178
Step-by-step explanation:
Answer:
- 5
Step-by-step explanation:
given,
the relation is y=2x+1
if x=-3 than, y =2x+1
=2 * (-3)+1
= -6+1
-5
hence, the required answer is - 5
I found any one solution of given question.
Answer:
Loss = 16.67%
Step-by-step explanation:
Assume cost price(CP) of 1 article = x
Therefore cost price of 25 articles = 25x
Given cost price of 25 article = selling price of 30 articles
Clearly, it is a loss.
Selling price(SP) of 30 articles = 25x


that is a very complicated question with alot of variable to figure out
