The solution

You have entered [src]
10*x + 9 = 7*x
$$10 x + 9 = 7 x$$
Detail solution
Given the linear equation:
10*x+9 = 7*x

Move free summands (without x)
from left part to right part, we given:
$$10 x = 7 x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -9$$
Divide both parts of the equation by 3
x = -9 / (3)

We get the answer: x = -3
