(7x-1)-(9x+3)=5 equation

The teacher will be very surprised to see your correct solution 😉

You have entered [src]

7*x - 1 + -9*x - 3 = 5

\left(- 9 x - 3\right) + \left(7 x - 1\right) = 5

Simplify

Detail solution

Given the linear equation:

(7*x-1)-(9*x+3) = 5

Expand brackets in the left part

7*x-1-9*x-3 = 5

Looking for similar summands in the left part:

-4 - 2*x = 5

Move free summands (without x)
from left part to right part, we given:

- 2 x = 9

Divide both parts of the equation by -2

x = 9 / (-2)

We get the answer: x = -9/2
