Question

5.(y-x)-2(3y-1)=0 me ajuda a resolver essa equação

Answer 1

5.(y-x)-2(3y-1)=0
5y - 5x -6y + 2 = 0
-y - 5x = -2
 y + 5x = 2
 y = 2 - 5x

Answer 2

5.(y-x)-2(3y-1)=0
5y - 5x -6y + 2 = 0
-y - 5x = -2
 y + 5x = 2
 y = 2 - 5x

x=1
y+5x=2
y+5.1=2
y+5=2
y=2-5
y=-3
y+5x=2
-3+5x=2
5x=2+3
5x=5
x=5/5
x=1
