Given -:

EF = 2X-7

FG = 4X-20

EG = 21

FIND OUT

EF =?

FG = ?

To proof

as given in the question

we have the value of EF = 2X-7 , FG = 4X-20 and EG = 21

Thus we have

EG = EF + FG

21 = 2X-7 + 4X- 20

21 = 6x - 27

48 = 6x

x = 8

Hence proved

Now put this value

EF = 2\times 8 - 7\\EF = 9

Now

FG = 4\times 8 - 20\\FG = 12

Hence proved

zubka84 [21]
Well, you can cancel out the b and e, so a/c = f/d.

Then you cancel out a on the left side of the equation by multiplying both sides by 1/a which then gives you c = f/ad.

Hope this helps!

The system of equations is graphed on the coordinate plane.
ehidna [41]

Answer: The solution is (3, -2)

This means that x = 3 and y = -2 pair up together.

=====================================================

Explanation:

The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).

-----------------

As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation

y = (-5/3)x + 3

y = (-5/3)*3 + 3

y = -5+3

y = -2

The first equation is confirmed. Let's check the second equation

y = (1/3)x - 3

y = (1/3)*3 - 3

y = 1 - 3

y = -2

Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.
