Answer:

I don't know if you want the beginning to so-

Variable - A unknown value represented by a set letter.

4x+6 = 26

(Incase: Subtract 6 from 6, and 6 from 26. 6 cancels out, and 26-6 is 20. Divide both sides by 4. And x=5)

And the answer to the question is: -27 is the smallest, and then the 3 consecutive numbers are -27, -28, and -29.

Y - 8 = -10<br> How do I verify the solution ?
prisoha [69]

Answer:

y = -2

Step-by-step explanation:

<u>SOLUTION :-</u>

Solve the equation.

  • Add 8 to both sides in order to isolate the equation.

=> y - 8 + 8 = -10 + 8

=> y = -2

∴ y = -2

<u>VERIFICATION :-</u>

To verify the solution of y , just put the solution (y = -2) in place of y in equation and check whether L.H.S = R.H.S.

L.H.S :-

-2 - 8 = <u>-10</u>

R.H.S. :-

<u>-10</u> (already given)

⇒L.H.S. = R.H.S. (verified)

Helppp!!!! please!!!
zheka24 [161]

Answer:

D. 104

Step-by-step explanation:

We know that xy and yz are supplementary to each other

That means they add up to 180

We can set up an equation with this information

(4x+32)+(2x+40)=180

6x+72=180

6x=108

x=18

Now that we know what x is, we can plug it into 4x+32 to find degree of xy

4(18)+32

72+32
