The decimal adds a zero every time the powers of ten increase for example if u do                                                                                                                                                                                                                                                                                                                                                                                                                 1 x  10^{2}=100 if u do                                                                                                1x10x^{3}=1,000

Using the problem below, solve and explain how you got the solution to the system of equation.
Paul [167]

Answer:

(5, -3)

y= -3

x= 5

Step-by-step explanation:

-x-2y=1

x+y=2

solve the equation

-x-2y=1

x=2-y

substitute the value of x into an equation

-(2-y)-2y=1

remove parenthesis

-2-y-2y=1

subtract y to 2y

-2-y=1

add 2 from both sides

-y=3

divide both sides by -y

y= -3

substitute the value of y into an equation

x=2-(-3)

remove parenthesis

x=2+3

add 2 to 3

x=5

(5,-3)

what is 9z+2=6z-10-z-4 we have to do something called railroad tracks where we put lines down the sides of the equal sign but I
Colt1911 [192]
You want to solve for 'z'.
First combine like terms on either side of the equal sign.

Left side:  9z +2  ----> No like terms, leave alone

Right side: 6z - 10 -z - 4  ----> circle like terms and add
                    6z -z = 5z
                   -10 -4 = -14
Now the equation is:
9z + 2 = 5z - 14

Get all the 'z' terms on the left side and all the numbers on right side.
You can move a term to the other side if you flip the sign.

Move 5z to left side, flip the sign to -5z
Move '2' to right side, flip the sign to -2

9z - 5z = -2 -14

Add like terms
4z = -16

Divide by 4 on both sides
z = -4
