Question

Регион уравнение 19*6*(15-3*y+3-y):3=228:3

Answer 1

$19*6*frac{15-3*y+3-y}{3}=frac{228}{3}\114*frac{18-4y}{3}=76\38(18-4y)=76\18-4y=frac{76}{38}=2\y=frac{18-2}{4}=4$

Answer 2

19•6•( 15 - 3•y + 3 - y ) : 3 = 228 : 3
114•( 18 - 4y ) = 76 • 3
18 - 4y = 228 : 114
4y = 18 - 2
y = 16 : 4
y = 4
