3y = -x+11

2x+4y= 14

Solve the system.

x = -1

y = 4

Step-by-step explanation:

3y = -x + 11

2x + 4y = 14

Rearrange equation 1

It becomes

x + 3y = 11

2x + 4y = 14

Multiply equation 1 by 4 and equation 2 by 3

We have

4x + 12y = 44

6x + 12y = 42

Subtract equation 2 from one

We have

-2x = 2

Divide both sides by-2

x = -2/2

x = -1

Now substitute-1 for x in any of the equations to get y .

Using equation 1, we have

-1 + 3y = 11

Add 1 to both sides of the equation

-1 + 1 + 3y = 11 + 1

3y = 12

Divide both sides by 3

3y/3 = 12/3

y = 4

hi how are you doing today, if you need just ask me.

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
