The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
7*x+9 = 4*x+3
Move free summands (without x)
from left part to right part, we given:
$$7 x = 4 x - 6$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -6$$
Divide both parts of the equation by 3
x = -6 / (3)
We get the answer: x = -2
