-2.5(-2-3x)+2.5(-4x-1)=-2x-4x

Mathematics
1 answer:
babymother [125]3 years ago
4 0

Answer:

x=−0.714286

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2.5(−2−3x)+2.5(−4x−1)=−2x−4x

(−2.5)(−2)+(−2.5)(−3x)+(2.5)(−4x)+(2.5)(−1)=−2x+−4x(Distribute)

(7.5x+−10x)+(5+−2.5)=(−2x+−4x)(Combine Like Terms)

Step 2: Add 6x to both sides.

Step 3: Subtract 2.5 from both sides.

Step 4: Divide both sides by 3.5.

x=−0.714286

One week Jenna rented 4 DVDs and 2 Video Games for $18, the next week she rented 2 DVDs and 1 video game for 9$. Find the rental
tangare [24]
To do this problem you have to create two equations. one would be 18=4x+3y
an the other would be 9=2x+y. in this eqaution X is the number of DVDs and Y is the number of Video games. Then you solve for Y in the second equation and you get y=-2x+9. After that you then input this equation in for the other equation and you will have 18=4x+3(-2x+9). you solve for X in this problem and then you take the answer of x and put it in for x in the other equation. 
so, 18=4x-6x+27
subtract 27 and add the 4x and -6x
-9=-2x
x=4.5
after this you put it in the other equation
9=-2(4.5)+y
multiply the -2 and 4.5
9=-9+y
add the 9
y=0
