Question

Solve for 'x' and cheak the answer

d.
$\frac{x}{2} - 3 = \frac{x}{3} + 3$
f.
$\frac{x}{3} + \frac{x}{5} + \frac{x}{15} = 3$
will be marked as brainiest ​

Answer 1

Step-by-step explanation:

1st one

x/2-3=x/3+3

so x/2-x/3=6

so x=36

now checking

lhs :-

36/2-3

=15

rhs:-

36/3+3

=15

*thus lhs=rhs(hence proved)

2nd one

x/3+x/5+x/15=3

so 9x/15=3

so x=5

checking

lhs:-

5/3+5/5+5/15

=5/3+1+1/3

=5+3+1/3=3 =rhs

thus lhs=rhs (hence proved)
