Find the determinant of G

1 answer:

3 0

The determinant is found by the formula ad-cb

where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0

12x2 = 24
-6x0 =0

24-0 = 24
the determinant = 24

Hey there!☺

$Answer:\boxed{x=2}$

$Explanation:$

$3(-x+4)=7x-8$

Let's start by simplifying both sides. First, we distribute.

$(3)(-x)+(3)(4)=7x+-8$

$-3x+12=7x+-8$

$-3x+12=7x-8$

Now let's subtract 7x from both sides.

$-3x+12-7x=7x-8-7x\\-10x+12=-8$

Now we will subtract 12 from both sides.

$-10x+12-12=-8-12\\-10x=-20$

In our last/final step, we will divide both sides by -10.

$\frac{-10x}{-10}=\frac{-20}{-10}$

Now simplify -20/-10.

$-20/-10=2$

$x=2$

Hope this helps!
