Step-by-step explanation:
Bordeaux mixture
Bordeaux mixture (also called Bordo Mix) is a mixture of copper(II) sulphate (CuSO4) and quicklime (CaO)used as a fungicide. It is used in vineyards, fruit-farms and gardens to prevent infestations of downy mildew, powdery mildew and other fungi. It is sprayed on plants as a preventive treatment; its mode of action is ineffective after a fungus has become established. It was invented in the Bordeaux region of France in the late 19th century. If it is applied in large quantities annually for many years, the copper in the mixture eventually becomes a pollutant. As such its sale and use is illegal in Great Britain and most of the European Union. Despite this, it has been promoted as an 'organic' pesticide.
Multiply both the sides by 15
⇒ 5x + 15 = 21
Move constant to the right
⇒5x = 21-15
Subtract the numbers
⇒ 5x = 6
Divide both the sides by 5
6
X =
or 1.2
... The value of x is
Verification :
1.2 3 +1= 7 5
Divide and convert fraction into decimal
⇒0.4+1=1.4
Add the numbers
⇒ 1.4 = 1.4
... LHS = RHS ✓✓
