See below

Explanation:

# 4/5 x + 7/2 = 3/10#

First take LCM on both the sides

#-> (8x + 35 = 3)/10 #

Now you can eliminate the LCM

#-> 8x + 35 = 3#

#-> 8x = 3 - 35#

#-> 8x = -32#

Divide both sides by 8

#-> cancel8^1*x/(cancel8) = cancel(-32)^-4/(cancel8)#

#-> x = -4#

take LCM and solve

Explanation:

taking LCM in
#4/5x + 7/2 = 3/10#

#=> 8/10x + 35/10 = 3/10#

#=> 8x + 35 = 3#

#=> 8x =-32#

#=> x=-4#
