Step-by-step explanation:
Given
2BD = 7BT , then
2(d - b ) = 7(t - b) ← distribute both sides
2d - 2b = 7t - 7b ( add 7b to both sides )
2d + 5b = 7t, thus
2 + 5
= 7t
+
= 7t
= 7t , thus
t = =
Hence T = (3, 5 )
We need to solve for x
To get x alone we need to remove the denominator 5
To remove denominator 5 we multiply by 5 on both sides
2x = 50
2x means 2 times x
2 is multiplied with x. so to remove 2 we divide by 2
So x= 25
Answer:
The cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Step-by-step explanation:
Let us assume this is a simple interest scenario.
Let D be the cost of desktop
Let L be the cost of laptop
Given- the laptop cost $150 more than the desktop.
So,
The total finance charge for 1 year is given by :
Substituting the value of L here, we get;
=>
=>
=>
=>
D = $1750
As
So,
L = $1900
We can check this :
=>
=>
So, the cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
