18-7x=10-3(x+4) equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
18-7*x = 10-3*(x+4)
Expand brackets in the right part
18-7*x = 10-3*x-3*4
Looking for similar summands in the right part:
18 - 7*x = -2 - 3*x
Move free summands (without x)
from left part to right part, we given:
−7x=−3x−20Move the summands with the unknown x
from the right part to the left part:
−4x=−20Divide both parts of the equation by -4
x = -20 / (-4)
We get the answer: x = 5
