Show work

x = 1 and y = 5

We already know that x=y-4 so place the value of, "x" in the first equation, -10x+3y=5. So solve the steps like this:

-10(y-4) + 3y = 5

-10y + 40 + 3y = 5

-7y= 5-40

-7y= -35

y= -35/-7

y= 5

Now place the value of y in the first equation.

-10x + 3(5) = 5

-10x + 15 = 5

-10x= 5-15

x= -10/-10

x= 1

So x is 1 and y is 5

Brainliest pls if i am correct!

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
