Step-by-step explanation:

The value of y for the expression will be y = (-x-10)/ 5.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is x-5y-10=2x. The solution of y for the expression will be calculated as,

x-5y-10=2x

x - 2x -10 = 5y

5y = -x -10

y = ( -x -10) / 5

1) Yes, one object can apply force to another without even touching it. For instance, it is called magnetic and electrostatic force, electrostatic and magnetic force is a different type of force that can pull or push another object without having to touch them together. For example, think of a magnet, if you put the North Pole side of the magnet and the South Pole side of the magnet they will pull each other together because of the different electric charges. But the two north poles will push each other away, like others say they repel each other.

2) A magnet does not have to be touching an object to attract it or repel it. This works because magnetism can work over a distance. Even though we can't actually see magnetic force, we can see what the force does to things around it.

-3 (3x-3) = 4/5 (5x-10)

Answers

Answer:

x=17/13

Step-by-step explanation:

-3(3x-3)=4/5(5x-10)

-9x+9=4x-8

-13x= -17

x=17/13

Answer:

[tex]1\frac{4}{13}[/tex]

Step-by-step explanation:

-3 (3x-3) = 4/5 (5x-10)

-----------------------------

This also equals to:

-3*(3x-3)=4/5*(5x-10)

-----------------------------

Start by opening the parentheses:

-3*(3x-3)=4/5*(5x-10)

Then use distributive property:

(-3*3x) + (-3*-3)= (4/5*5x) + (4/5*-10)

Simplify the equation:

(-3*3x) + (-3*-3)= (4/5*5x) + (4/5*-10)

-9x+9= 4x-8

    +8       +8

-9x+17= 4x

+9x      +9x

17= 13x

÷13 ÷13

17/13=x
