=5x/2+3=21/8 (combine multiplied terms into a single fraction).
= 5x/2+2.3/2=21/8 ( find common denominator).
= 5x+2.3/2=21/8 (combine fraction with common denominator).
=5x+6/2=21/8 ( multiply 2.3 which is in last step).
=2(5x+6/2)=2×21/8
=5x+6=2×21/8
=5x+6=21/4
=5x+6-6=21/4-6 ( subtract 6 into both sides).
=5x= -3/4
=5x/5=-3/4/5
= So, the value of x=-3/20
