The first one is the answer.
Sketch the graph of the two by substituting x as 1, 2, 3 and you will see that the two graphs look exactly the same but seem to be reflected through the mirror line of the x-axis
⇒ Solution
1) Simplify
<span>4x−20−8=−28+6x
2) </span>Simplify 4x−20−8 to 4x−28
<span>4x−28=−28+6x
3) G</span>roup all terms
<span>4x−28=6x−28
4) </span>Cancel −28 from eachside
<span>4x=6x
5) </span>Move all of the terms to one side
<span>4x−6x=0
6) </span>Simplify equation 4x−6x to −2x
<span>−2x=0
</span>7) Divide each side by <span><span>−2</span></span>
<span><span>x=0</span></span>
If the scale is 2 inches: 5 yards, then 6 inches would be 15 yards.
$1400 / 7 = $200
$200 x 2 = $400
$1400 - $400 = $1000
John has $1000 left in his account.
