What is the value of x in 5x - 4 = 7x + 8?

Answer 1

Q: What is the value of x in 5x-4=7x+8

A: -6

SBS: 5x-4-7x=7x+8-7x -2x-4=8 -2x -4+4 --> 8+ 4-2x=12

(DIVIDE)

-2x/-2 = 12/-2= -6

Answer 2

x = -6

Explanation:

To find the value of x in the given equation, we have to solve for x.

5x - 4 = 7x + 8

Add 4 to both sides.

5x = 7x + 12

Subtract 7x from both sides.

-2x = 12

Divide both sides by -2.

x = -6

So the value of x would be -6.

I hope this helps. Happy studying.
