7x-8y=13 solve for y

Sagot :

get y alone
so
-8y=13-7x (by subtracting 7x from both sides)
now you still want y by itself so you divide by -8
leaving you with
y=-13/8 + 7/8

y = 7x/8 - 13/8

What is equation ?

Equation is a mathematical statement in which two mathematical expression of both sides of a "=" sign are equal.

Example : 4x-5y=2x+3

How to find the value of y ?

The given equation is, 7x-8y=13

First we have to subtract 7x in both sides,

⇒ -8y=13-7x

Now we have to multiply '-' sign in both sides,

⇒ 8y=-13+7x

Now, we have to divide right hand side by 8,

⇒ y = -13/8 + 7x/8

Rearranging we get,

⇒ y = 7x/8 - 13/8
