Question

solve for y,8y-9=4y+3

Answer 1

Answer:

Simplifying

8y + -9 = 4y + 3

Reorder the terms:

-9 + 8y = 4y + 3

Reorder the terms:

-9 + 8y = 3 + 4y

Solving

-9 + 8y = 3 + 4y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4y' to each side of the equation.

-9 + 8y + -4y = 3 + 4y + -4y

Combine like terms: 8y + -4y = 4y

-9 + 4y = 3 + 4y + -4y

Combine like terms: 4y + -4y = 0

-9 + 4y = 3 + 0

-9 + 4y = 3

Add '9' to each side of the equation.

-9 + 9 + 4y = 3 + 9

Combine like terms: -9 + 9 = 0

0 + 4y = 3 + 9

4y = 3 + 9

Combine like terms: 3 + 9 = 12

4y = 12

Divide each side by '4'.

y = 3

Simplifying

y = 3

Answer 2

Answer:

=> y = 3

Step-by-step explanation:

Given that:-

$8y-9=4y+3$

To find:- The value of the expression.

Here we will use the transposition method.

As we have,

=> $8y-9=4y+3$

Now, add $9$ on both the sides

=> $8y-9+9=4y+3+9$

=> $8y=4y+3+9$

Add the numbers, we get

=> $8y=4y+12$

Now, subtract $4y$ on both sides

=> $8y-4y=4y+12-4y$

=> $4y =12$

Divide both sides by $4$, we get

=> $y = 3$

Hence, the required solution is 3.
