Question

Pls help- studying for midterms!!!!!

Answer 1

Answer:

x= -43/2

Step-by-step explanation:

$\frac{1}{5}x +\frac{3}{10} =-4$

To add or subtract fractions, we need to have the same denominator. We can do that by cross multiplying : $\frac{1}{5}x$ + $\frac{3}{10}$  for the numerator, and multiply both denominators together to find our common denominator.

$\frac{10x+15}{50}=-4$

Now, cross multiply to solve for x.

$10x+15=-200$

$10x=-215$

$x=-\frac{43}2}$

Answer 2

1/5x+3/10=-4
1x/5+3/10=-4
1x/5+3/10=-4
x/5+3/10=-4
x=43/2
