Question

12y + 6 - 6y - (-9y + 4) = 3y -9​

Answer 1

To find : value of y

Solution:

Given equation :  $12y + 6 - 6y - (- 9y + 4 ) = 3y - 9$

• we simplify each side of equation  by combining like terms together

⇒     $12y + 6 - 6y + 9y - 4 = 3y - 9$

• we use addition and subtraction to isolate variable term on one side of equation.

⇒     $12y -6y + 9y - 3y = -6 + 4 - 9$

⇒       $12y = -11$

• then we divide to solve for the variable

⇒    $y = \frac{-11}{12}$

Hence , value of y is $\frac{-11}{12}$
