✔ 最佳答案
1-3(y-5)=4(2-3y)
1-3y+15=8-12y Distributed property
16-3y=8-12y Simplify
-3y+12y=8-16 transpose 12y to the left and 16 to the right
9y=-8 divide both sides by 9
y=-8/9 or -0.888 answer

1 - 3(y - 5) = 4(2 - 3y)
1 - 3*y + 3*5 = 4*2 - 4*3y
1 - 3y + 15 = 8 - 12y
12y - 3y = 8 - 1 - 15
9y = -8
y = -8/9

1st, distribute:
1-3y+15=8-12y

16-3y=8-12y

Subtract 16 from both sides:
-3y= -8-12y

Add 12y to both sides:
9y= -8

Divide by 9 on both sides:
y= -8/9

Hope this helps!! :)

1-3(y-5)=4(2-3y)
1-3y+15=8-12y
12y-3y=8-1-15
9y=-8
y=-8/9

1 - 3 (y -5) = 4 (2 -4y)
1 -3y - 15 = 8 - 16y
-3y - 14 = 8 - 16y
13y = 24
y = 24/13
y = 1.8

1-3(y-5) = 4(2-3y)

This is tricky with the order of operations.

Multiply:
1 - 3y + 15 = 8 - 12y

Group like terms:
1 + 15 - 8 = -12y + 3y

Simplify:
8 = -9y
-8/9 = y
2008-12-10 2:46 pm
1-3y+15=8-12y
16-3y=8-12y
-8``````-8
8-3y=-12y
8=-9y
y=-8/9
參考: the other guy but without the subtraction mistake

y = -9/8
2008-12-10 2:41 pm
y = -8/9
