Solution to 7(y-3) =2(y-9) +2y

dolphi86 [110]

<h3>The value of y is equal to 1.</h3>

7(y - 3) = 2(y - 9) + 2y

Distributive property.

7y - 21 = 2y - 18 + 2y

Combine like terms.

7y - 21 = 4y - 18

Subtract 4y from both sides.

3y - 21 = -18

Add 21 to both sides.

3y = 3

Divide both sides by 3.

y = 1

Answer:-m or m+3

Step-by-step explanation:

$x^{2} -3x -(m^{2}+3m) =0\\\\x^{2} -3x -m^{2} -3m=0\\$

$x^{2} -m^{2} -3x - 3m=0$

Applying difference of two squares

⇒( $x^{2} -m^{2}$ )=(x+m)(x-m)

Substituting this for ( $x^{2} -m^{2}$ )

Factorising -3x-3m=-3(x+m)

(x+m)(x-m)-3(x+m)=0

since we have double (x+m),we'll pick one

⇒(x+m)=0

or (x-m-3)=0

⇒x=-m or x= m+3
