Question

Re-arrange 4y=2x-7 to get x

Answer 1

x = (4y + 7)/2.


First, switch sides so the variable x is on the left of the equation: 2x - 7 = 4y.
Next, add 7 to both sides of the equation:
2x - 7 + 7 = 4y + 7
2x = 4y + 7
Now, we isolate the variable, x. To do this, divide both sides by 2:
2x/2 = (4y + 7)/2
x = (4y + 7)/2.

Answer 2

Hello!

Answer:

`\Large \boxed{\sf x = 2y + 3.5}`

Explanation:

→ We want to solve x in this equation:

`\sf 4y=2x-7`

◼ Subtract 4y from both sides:

`\sf 4y-4y=2x-7-4y`

◼ Simplify both sides:

`\sf 0=2x-7-4y`

◼ Subtract 2x from both sides:

`\sf 0-2x=2x-7-4y-2x`

◼ Simplify both sides:

`\sf -2x=-7-4y`

◼ Divide both sides by -2:

`\sf (-2x)/(-2) = (-7-4y )/(-2)`

◼ Simplify both sides:

`\sf x = (7+4y )/(2)`

`\boxed{\sf x = 2y + 3.5}`

Conclusion:

In the equation 4y = 2x - 7, x is equal to 2y + 3.5.
