a) 3(2x - 6y) + 8y
= (6x -18y) + 8y
= 6x - 10y
b) 2(5y + 4) - 4(5-y)
= (10y + 8) - 20 + 4y
= 14y -12

a)
3(2x - 6y) + 8y
= 6x - 18y + 8y
= 6x - 10y
b) 2(5y + 4) - 4(5 - y)
= 10y + 8 - 20 + 4y
= 14y - 12
Hope it helps

6x-18y +8y
10y+8-20+4y=
14y-12 =0
Y=12/14
y=6/7
solving for x:
16x-18(6/7)X+8(6/7) =0
16x-104/7+48/7=0
16(7)X=104-48
112x=56
x=56/112
x=28/56
x=1/2

a)6x-18y+8y
6x-10y
b)10y+8-20+4y
14y-12
if you want it factored
a)2(3x-5y)
b)2(7y-6)
if the equation is =0
using b
14y/14=12/14
y=6/7
then substitute
6x=10(6/7)
(6x=60/7)7
42x/42=60/42
x=10/7
