• 45x[ 4/9 = 1/5 + 1/x ]

To do,

• To multiply 45x to all the terms

Given that,

• 45x[ 4/9 = 1/5 + 1/x ]

Distribute property of Multiplication over Addition ,

• a ( b + c ) = ab + ac

________________________________

As it says,mutiply 45x to all the terms.

This is required to get rid of fractions.

See the steps below:

• 45x [ 4/9 = 1/5 + 1/x ]
• 45x (4/9) = 45x(1/5) + 45x(1/x) ==> Multiply
• 5x(4) = 9x + 45 ==> Simplify
• 20x = 9x + 45 ==> End result without fractions.

■45x * 4/9 = 45 * 1/5 + 45 x * 1/x

■5x * 4=9x + 45

■20x = 9x + 45
