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
For this case we must find the value of the variable "x" of the following expression:
So:
We multiply by 7 on both sides of the equation:
We add 3 to both sides of the equation:
Equal signs are added and the same sign is placed.
