After my salary was increased by $16\%,$ it was $\$55{,}680$. What was my salary before the increase?

The salary before the increase was $48000.

Step-by-step explanation:

Let us assume,

The previous salary before the increase be 'x'.

It is given that,

After increased by 16%, the salary turned to $55680.

Therefore, take the previous salary x as 100%. The increase of 16% from x will be 116%.

So, 116% of x equals to the increased salary $55680.

To find the value of x :

⇒ (116/100) × x = 55680

⇒ (1.16) × x = 55680

⇒ x = 55680 / 1.16

⇒ x = 48000

∴ The salary before the increase was $48000.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
