48=y+5y

pretend that there is a 1 in front for the y

48=1y+5y

add the like terms first

1y+5y=6y

48=6y

divide both sides by 6 to get y by itself

48/6=6y/6

8=y

answer:

y=8

Answer:

y = 8

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

48 = y + 5y

<u>Step 2: Solve for </u><em><u>y</u></em>

  1. Combine like terms:                    48 = 6y
  2. Divide 6 on both sides:               8 = y
  3. Rewrite:                                        y = 8

<u>Step 3: Check</u>

<em>Plug in y into the original equation to verify it is a solution.</em>

  1. Substitute in <em>y</em>:                    48 = 8 + 5(8)
  2. Multiply:                               48 = 8 + 40
  3. Add:                                     48 = 48

Here we see that 48 does indeed equal 48.

∴ y = 8 is a solution of the equation.

Dvinal [7]

Answer:

Lets assume a polynomial

Here GCF is 5z

all terms are divisible by 5z. so greatest common factor is 5z

One form of polynomial is

We factor the polynomial further

Other form of polynomial is

 and  are the two forms of polynomial

First form   is created by taking out GCF 5z

<h2>SEcond form   is created by factoring x^2 + 5x + 6</h2><h2></h2><h2></h2><h2></h2><h2>hope this help u !!!</h2><h2></h2>

8090 [49]
Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,

\bf y=\cfrac{6}{5}x+9\implies -\cfrac{6}{5}x+y=9
