7x-10x+18+2x=-5.0000
inysia [295]

Simplifying

7x + -10x + 18 + 2x = -5

Reorder the terms:

18 + 7x + -10x + 2x = -5

Combine like terms: 7x + -10x = -3x

18 + -3x + 2x = -5

Combine like terms: -3x + 2x = -1x

18 + -1x = -5

Solving

18 + -1x = -5

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-18' to each side of the equation.

18 + -18 + -1x = -5 + -18

Combine like terms: 18 + -18 = 0

0 + -1x = -5 + -18

-1x = -5 + -18

Combine like terms: -5 + -18 = -23

-1x = -23

Divide each side by '-1'.

x = 23

Simplifying

x = 23

How do you this??<br><br> Scientific notation
Airida [17]
So Scientific Notation is a "simplified version" of a number. For example, is your number is 2,345, the scientific notation would be 2.345 * 10³. 

If it was 0.023, then the scientific notation would be 2.3 * 10^-2. 

Scientific notation is found by moving the decimal place to the left or right, until only one digit is left to the left of the decimal; it has to be greater than 1, but less than ten. If you move the decimal place to the right, it's a negative power of 10. If you move it to the left, it is a positive power of 10.


Hope this helps!
