Answer:
b = c(a - 6x )
Step-by-step explanation:
Given
6x + = a ( subtract 6x from both sides )
= a - 6x ( multiply both sides by c to clear the fraction )
b = c(a - 6x)
so hmm the idea behind the elimination, is to make the value atop or below, of either variable, the same but with a negative sign
so hmmm say... we'll eliminate "y"
so... let's see, we have 2y and 5y, both positive
what do we multiply 2y to get a negative -5y, that way, -5y +5y = 0 and poof it goes
well let's see, let's try "k"
so.. if we multiply 2y by -5/2, we'll end up with -5y
well, let's multiply that first equation then by -5/2
so.. now we know x = 1.... so let's plug that in say hmmm 2nd equation
Answer:
The original cost of Car at the time of purchased = 20500 unit
Step-by-step explanation:
According to question ,
Mr. Kork selling cost of his Car = 8400 unit
And Selling cost is 200 more than two fifths of the purchased cost of Car .
Let the Purchased cost of car = X unit
So, AS per question
200 + × x = 8400
Or, × x = 8400 - 200
i.e × x = 8200
So , x = 8200 ×
∴ x = 4100 × 5 = 20500 unit
Hence The original cost of Car at the time of purchased = 20500 unit Answer
