How do i solve 4x - 2y = 22 and 2x + 4y = 6 using substitution and elimination?
Fiesta28 [93]

substitution and elimination means that you need to use one equation and substitute it in place of some variable in the other equation.

Consider the above two equations.

Take equation 1, which is 4x-2y=22 => x=(22+2y)/4

substitute the x value gained above in equation 2.

so, 2((22+2y)/4)+4y=6

22+2y+8y=12 => 10y = -10 => y= -1.

Substitute y= -1 in x value obtained in the beginning.

So, x= (22 - 2)/4 => 5.

There fore, x= 5 and y= -1

Hope it helps.

What is the fraction for 45 divided by 20 please show work
lianna [129]

Answer:

9/4

Step-by-step explanation:

The divide symbol is also the line that separates the numerator and the denominator, so 45÷20 can also be written as 45/20.

We can see that both 45 and 20 are divisible by 5, so we can simplify the fraction down to 9x5/4x5, and then we cancel out the 5s and are left with 9/4

Ulleksa [173]

Answer:

My answer came out to -22.

Step-by-step explanation:

Start multiplying from left to right:

Two negatives multiplied are positive:

-2.2·(-2)=4.4

A negative and a positive multiplied equal a negative:

4.4·(-1)=-4.4

-4.4·5=-22
