Since 1/4 has been taken off, 3/4 are still left on. The sale price is 3/4 of the regular price, so that's the prop constant.

$ale = 0.75 regular.

If the regular price is $29, then

$ale = 0.75 ($29) = $21.75

Solve the simultaneous equation<br> 2x+4y=1<br> 3x+5y=7b
Lyrx [107]

Step-by-step explanation:

  • 3x+5y=7b equation 1
  • 2x+4y=1

2x=-4y+1

  • x=(-4y+1)/2
  • x=(-4y+1)/2 in equation 1

3×(-4y+1)/2+5y=7b

(-12y+3)/2+5y=7b

(-12y+3+10y)/2=7b

(-12y+3)/2=7b

-12y+3=14b

-12y=14b-3

  • y=3-14b/12
  • y=3-14b/12 in x=(-4y+1)/2

x=(-4×{3-14b/12}+1)/2

x=(-3+14b)/3+1/2

x=14b/3×1/2

  • x=7b/3
