4(1-2x)-7+3x=12 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
4*(1-2*x)-7+3*x = 12
Expand brackets in the left part
4*1-4*2*x-7+3*x = 12
Looking for similar summands in the left part:
-3 - 5*x = 12
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 15$$
Divide both parts of the equation by -5
x = 15 / (-5)
We get the answer: x = -3
