3x-8 = 8x-33
3x-8x = -33+8
-5x = -25
x = -25/-5
x = 5
The equivalent fraction of 4/20 is 3/15
Yes. The dependent variable depends on the independent variable.
Let the cost price of article be x :
x + x × ( 15/100 ) = 2300
x + x × ( 5 × 3 / 5 × 20 ) = 2300
x + x × ( 3 / 20 ) = 2300
x + ( 3 × x / 20 ) = 2300
x + ( 3x / 20 ) = 2300
( 20x / 20 ) + ( 3x / 20 ) = 2300
20x + 3x / 20 = 2300
23x / 20 = 2300
Multiply both sides by 20
( 23x / 20 ) × 20 = 2300 × 20
23x = 2300 × 20
23x = 23 × 2000
Divide both sides 23
23x ÷ 23 = ( 23 × 2000 ) ÷ 23
x = Rs 2000
We want to solve this:
54x + 64 ≥ 49x + 59
First, subtract 49x from both sides and you would get:
5x + 64 ≥ 59
Then subtract 64 from both sides:
5x ≥ -5
Divide both sides by 5:
x ≥ -1
