Question

X + y = 7, for x





....

Answer 1

Hey there!☺

`Answer:\boxed{x=-y+7}`

`Explanation:`

`x+y=7`

The first/last step we have is to add -y to both sides.

`x+y+-y=7+-y\\x=-y+7`

`x=-y+7` is your answer.

Hope this helps!☺

Answer 2

x = -y + 7

or

x = 7 - y

Explanation:

x + y = 7

Step 1: Subtract y from both sides to get x alone.

x + y = 7

-y -y

x = 7 - y

Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.
