Answer:
x= -43/2
Step-by-step explanation:
[tex]\frac{1}{5}x +\frac{3}{10} =-4[/tex]
To add or subtract fractions, we need to have the same denominator. We can do that by cross multiplying : [tex]\frac{1}{5}x[/tex] + [tex]\frac{3}{10}[/tex] for the numerator, and multiply both denominators together to find our common denominator.
[tex]\frac{10x+15}{50}=-4[/tex]
Now, cross multiply to solve for x.
[tex]10x+15=-200[/tex]
[tex]10x=-215[/tex]
[tex]x=-\frac{43}2}[/tex]
