5+4g+8=1 find the solution to the equation
deff fn [24]

Answer:

<h2>g = - 3</h2>

Step-by-step explanation:

5+4g+8=1

To solve the equation first group like terms.

Send the constants to the right side of the equation

That's

4g = 1 - 5 - 8

Simplify

4g = - 12

Divide both sides by 4

g =  -  \frac{12}{4}

We have the final answer as

<h3>g = - 3</h3>

Hope this helps you
