Question

6g+5 =-2(1+2g) ------------------

Answer 1

Answer:

g= -7/2

Step-by-step explanation:

First expand the brackets

6g+5=-2+4g

minus the least number of g's to eliminate it on one side

-4g on both sides leaves us with

2g+5=-2

make g the subject

-5

2g= -2-5

2g= -7

÷2

g= -7/2

or

g= -7/2

Answer 2

Answer:

g: -7/10 or -0.7

Step-by-step explanation:

$6g+5=-2\left(1+2g\right)$

Apply the distributive law:-

$-2\left(1+2g\right)$

$=-2-4g$

$6g+5=-2-4g$

Now, we´ll Subtract 5 from both sides :-

$6g+5-5=-2-4g-5$

$6g=-4g-7$

Add 4g to both sides :-

$6g+4g=-4g-7+4g$

$10g=-7$

Now, divide both sides by 10:-

$\frac{10g}{10}=\frac{-7}{10}$

$g=-\frac{7}{10}$
