9+10(3x-10)=2 equation

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

You have entered [src]

9 + 10*(3*x - 10) = 2

$$10 \left(3 x - 10\right) + 9 = 2$$

Simplify

Detail solution

Given the linear equation:

9+10*(3*x-10) = 2

Expand brackets in the left part

9+10*3*x-10*10 = 2

Looking for similar summands in the left part:

-91 + 30*x = 2

Move free summands (without x)
from left part to right part, we given:
$$30 x = 93$$
Divide both parts of the equation by 30

x = 93 / (30)

We get the answer: x = 31/10
