$8(4x - 5)-12=20x-10$

$32x - 40-12=20x-10$

$32x -52=20x-10$

$32x -52 -20x=-10$

$12x -52=-10$

$12x =-10 +52$

$12x =42$

$x= \frac{42}{12}$

$x = \frac{7}{2}$

$x=3 \frac{1}{2}$ ≈ 3.5

Triss [41]

Number of bicycles sold this year= 582

%percent change= Iniitial -FInal/initial *100

%percent change= 655-582/582*100

%percent change=0.125 *100

%percent change=12.5%

Hence the percent change is 12.5%

-7 x - 2y = -13 <br> x - 2y = 11

VashaNatasha [74]

Well the first one would convert to
-2y= 7x-13 and the second one would be -2y=-x+11 and you solve from there (lmk if you need the steps) but your final answer would be. Y= -7/2x+ 13/2 and y=1/2x - 11/2
