Question

What is the value of x?
X-3/7 equals 4

Answer 1

Step-by-step

X-3/7 = 4

take -3/4 to the other side

x = 3/7 + 4

x = 3/7 + 28/7 (<=another way to write 4)

x = 31/7

Answer 2

For this case we must find the value of the variable "x" of the following expression:

$\frac {x-3} {7} = 4$

So:

We multiply by 7 on both sides of the equation:

$x-3 = 4 * 7\\x-3 = 28$

We add 3 to both sides of the equation:

$x = 28 + 3$

Equal signs are added and the same sign is placed.

$x = 31$

Answer:

$x = 31$
