Answer:

x = - 0.2

Step-by-step explanation:

4x+4= -0.3x+3

4x + 0.3x +4= 3     Add 0.3x to both sides

4.3x + 4 = 3      Simplify

4.3x  = 3 - 4    Subtract 4 from both sides

4.3x  =  -1    Simplify

4.3x  =  -1    Divide by 4.3 to isolate the variable

x = - 0.2

Step-by-step explanation:

Given,

Length of a rectangular prism ( l ) = 10 cm

Aaron and Maria collected shells one morning at the beach. Maria had 3 times as many as Aaron, but they would have had the same
Hoochie [10]
Let the amount of shells collected by Aaron be x and the amount of shells collected by Maria be y respectively. Then the following system of equations should be solved:
\left \{ {{3x=y} \atop {x+8=y-6}} \right.

First of all, express y out of first equation:
y=3x

Then, replace y in second equation with found expression and solve it:
x+8=3x-6
2x=14
x=14/2=7

Finally, replace x in first equation with found value and solve it too:
3*7=y
y=21

So, Aaron has found 7 shells while Maria has found 21.
