Solve the system using elimination: Help me please 12x - 8y = -12 6x + 4y = -30

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)

dedylja [7]

Answer:

Step-by-step explanation:

Distance from earth to moon =238,857 :

x-92350373 = 92589230

x= 238857

Distance from sun to moon. = 92,350,373 miles

Distance from earth to moon=184,939,603 miles

Distance from sun to moon. = 277,528,833 miles

Distance from earth to moon=238,857 miles

Distance from sun to moon. =92,828,087 miles
