Answer:
x=37/5 ; x=51/5
Step-by-step explanation:
x - 2/5= 7
here,
x-2/5
LCM of denominators(1 &5)=5
5 (LCM of denominators) divided by the denominator of x(which is 1)= 5/1 =5
then,
5 multiply with numerator of x (which is x) = 5x
again,
5 (LCM of denominators) divided by the denominator of 2/5(which is 5) = 5/5=1
then,
1 multiply with numerator of 2/5 (which is 2)= 1 x 2 =2
so,
the fraction is,
(5x-2)/7
which is = 7
so,
(5x-2)=35 [multiplied by 5 on both site ]
5x=35+2 [add 2 on both site]
5x=37
x=37/5 [divided by 5 on both site]
similarly,
x + 4/5 = 11
=>(5x+4)/5=11
=>5x+4=55 [multiplied by 5 on both site ]
=>5x=55-4 [subtraction by 4 on both site]
=>5x=51
=>x=51/5 [divided by 5 on both site]
