LUCKY_DIMON [66]

12x - 8y = -12  

6x + 4y = -30

Multiply the 2nd equation by 2, to make the Y coefficients opposite:

6x + 4y = -30 x 2 = 12x + 8y = -60

Now add the two equations:

12x -8y = -12 + 12x +8y = -60

=  24x = -72

Divide bothe sides by 24 to solve for x:

x = -72/24

x = -3

Now replace x with -3 in the first equation to solve for y:

12(-3) - 8y = -12

-36 - 8y = -12

Add 36 to each side:

-8y = 24

Divide both sides by -8 to solve for y:

y = 24 / -8

y = -3

X = -3 and y = -3

(-3,-3)

How you do this? I've been trying but I keep getting it wrong​
zmey [24]

Answer:

you plug in (y) with the top equation

Step-by-step explanation:

step 1: 2x+1/2x-1=-6

step 2: 2.5x-1=-6

step 3: 2.5x-1=-6

+1. +1

step 4: 2.5x= -5. Divide both sides by 2.5

-5/2.5 = -2

step 5: plug in your (x) to find (y)

y= 1/2(-2)-1

step 6: 1/2(-2) = -1

y=( -1)-1

y=-2

step 7: (x,y)= (-2,-2)

step 8: graph your coordinate

I hope that this helped you!

Please help me, I’m struggling

Answer:

28\sqrt{6}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

\sqrt{96}

= \sqrt{16(6)}

= \sqrt{16} × \sqrt{6}

= 4\sqrt{6}

Then

7\sqrt{96}

= 7 × 4\sqrt{6}

= 28\sqrt{6}
