(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

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

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 + 16*x = 5

Move free summands (without x)
from left part to right part, we given:
$$16 x = 1$$
Divide both parts of the equation by 16

x = 1 / (16)

We get the answer: x = 1/16
