The teacher will be very surprised to see your correct solution 😉
The solution
You have entered
[src]
9*x - 6*(x - 1) = 5*(x + 2)
$$9 x - 6 \left(x - 1\right) = 5 \left(x + 2\right)$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 5 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$- 2 x = 4$$
Divide both parts of the equation by -2
We get the answer: x = -2
9*x-6*(x-1) = 5*(x+2)
Expand brackets in the left part
9*x-6*x+6*1 = 5*(x+2)
Expand brackets in the right part
9*x-6*x+6*1 = 5*x+5*2
Looking for similar summands in the left part:
6 + 3*x = 5*x+5*2
Move free summands (without x)
from left part to right part, we given:
$$3 x = 5 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$- 2 x = 4$$
Divide both parts of the equation by -2
x = 4 / (-2)
We get the answer: x = -2
