How many terms are in this equation <br> 8y-6y^2/7^3
vlada-n [284]

Answer:

2

Step-by-step explanation:

You count terms that are seperated by - and + signs. Any type of fraction is considered one term.

So you count 8y as one term and the rest is a whole fraction so you also count that as one term.

You add all the terms together and you have 2 terms in this equation.

What is the solution to the equation 2(4-8x)+5(2x-3)=20-5x
9966 [12]

In this question, you're solving for x.

Solve for x:

2(4 - 8x) + 5(2x - 3) = 20 - 5x

Use the distributive property:

8 - 16x + 5(2x - 3) = 20 - 5x

8 - 16x + 10x - 15 = 20 - 5x

Combine like terms:

8 - 16x + 10x - 15 = 20 - 5x

8 - 6x - 15= 20 - 5x

-6x - 7 = 20 - 5x

Add 5x to both sides

-x - 7 = 20

Add 7 to both sides

-x = 27

Divide both sides by -1

x = -27

Answer:

x = -27
