✔ 最佳答案
5y - 8 = 2y - 2
5y - 2y - 8 = -2
3y = 8 - 2
y = 6/3
y = 2
5y - 8 = 2y - 2
3y = 6
y = 2.
Several people have already answered this question correctly. I will give you the steps.
1. Get the variable on only one side of the equation.
2. Choose to get rid of the 2y, its easier.
3. Subtract a 2y from both sides.
4. Get rid of the -8.
5. Add 8 to both sides.
6. Now get rid of the 3 that is divided into y.
7. Divide both sides by 3.
8. y = 2
given
5y-8=2y-2
so 5y-2y=-2+8
3y=6
hence y=2
you must ask no more stupid question like this one
5y-8=2y-2
+5y
8=7y-2
+2
7y=10
=3?
參考: Not a math expert.
5y-8=2y-2
5y-2y= (- 2)+8
3y = 6
y = 6/3
y=2
given
5y-8=2y-2
so 5y-2y=-2+8
3y=6
hence y=2
5y-8=2y-2
5y - 2y - 8 = 2y - 2y -2
3y - 8 = -2
3y -8 + 8 = -2 + 8
3y = 6
y = 6/3 = 2
