Question

5 solve the literal equation 2y = x+3 for x​

Answer 1

`\Large \boxed{\sf{x=2y-3}}`

Explanation:

`\sf We \ have \ the \ equation: \\ \\ 2y = x+3 \\ \\ We \ need \ x \ on \ one \ side \of \ the \ equation. \\ Solve \ for \ x. \\ \\ Subtract \ 3 \ from \ both \ sides. \\ \\ 2y-3=x+3-3 \\ \\ Simplify \ the \ equation. \\ \\ 2y-3=x`

Answer 2

`x=2y-3`

Explanation:

So we have the equation:

`2y=x+3`

And we want to solve it for x. In other words, we want to isolate the x-variable. To start, first subtract 3 from both sides. The right side cancels:

`(2y)-3=(x+3)-3\\2y-3=x`

And, that's it :)

If preferred, we can also switch the equation around using the symmetric property:

`x=2y-3`
