Is this your equation?
\(-4y+10=2(3y+1)\)?
OpenStudy (nicoleced):
no, its exactly how i wrote it.
OpenStudy (anonymous):
First you expand
-4y+10 =-2 (3y+1)
-4y + 10 = -6y – 2
The subtract 10 from each side
-4y + 10 - 10 = -6y – 2 – 10
Then add 6y to both sides
-4y = -6y – 12
-4y + 6y = -6y – 12 + 6y
2y = -12
Divide both sides by 2
2y / 2 = -12 / 2
y = -6

okay i have a couple more @trueseminole

.The same as last time, expand
-3x+1=-2 (4x+2)
-3x + 1 = -8x - 4
The subtract 1 from each side
-3x + 1 - 1 = -8x – 4 – 1
-3x = -8x - 5
Then add 8x to both sides
-3x = -8x – 5
-3x + 8x = -8x – 5 + 8x
5x = -5
Divide both sides by 5
5x / 5 = -5 / 5
y = -1
