The given expression is

5 \frac{13}{15} -1 \frac{2}{3}

First we write them in improper fraction. That is

= \frac{5*15+13}{15} - \frac{1*3+2}{3}

= \frac{88}{15} - \frac{5}{3}

And the LCD is 15 here.

\frac{88-25}{15} = \frac{63}{15}

Which can be reduced to

= \frac{21}{5} = 4 \frac{1}{5}

Can someone explain how I multiply both sides ?
stellarik [79]

Answer:

x=3

Step-by-step explanation:

Given,

1 = 1/(x-2)

Multiply both sides by (x-2),

1*(x-2) = 1/(x-2) * (x-2)

x-2 = 1

Adding 2 on both sides,

x-2+2 = 1+2

x = 3
