Answer: x=-7

Step-by-step explanation:

-30=5(x+1)

multiply the brackets

-30=5x+5

take away 5x from both sides of the equation

-30-5x=5

add 30 to both sides

-5x=35

divide both sides by -5

x=-7

coldgirl [10]
<span>.75(x+3)=.5(3)+x

</span><span> You already have 3 liters, and you are going to add x liters.
