Hi

4x-y=5

3x-7=2

We need to solve 3x-7=2 for x

Let's start by adding 7 to both sides

3x-7+7=2+7

3x=9

Now just divide both sides by 3 so we can find the value for x

3x/3=9/3

x=3

Now substitute 3 for x in 4x-y=5

4x-y=5

(4)(3)-y=5

-y+12=5

Now add -12

-y=12-12=5-12

-y=-7

Divide both sides by -1 so we can eliminate the negative sign

-y/-1=-7/-1

y=3

The answer is A

(3,7)

I hope that's help:0

Where does the length of day remain the same throughout the year?
djyliett [7]
Due to the inclination of the terrestrial axis, the day has different duration in several points of the planet, which also depends on the time of year. However, this duration remains the same throughout the year in the Equator, which is known as the imaginary line that divides the planet in two hemispheres: Northern Hemisphere and Southern Hemisphere.
