(7x-8)-(4x-5)=15 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
(7*x-8)-(4*x-5) = 15
Expand brackets in the left part
7*x-8-4*x+5 = 15
Looking for similar summands in the left part:
-3 + 3*x = 15
Move free summands (without x)
from left part to right part, we given:
$$3 x = 18$$
Divide both parts of the equation by 3
x = 18 / (3)
We get the answer: x = 6
