✔ 最佳答案
3x + 8 = 5x + 10-2x = 2
x = -1
12h - 5 = 11h + 5 - h
2h = 10
h = 5

3x + 8 = 5x + 10
-2x = 2
x = - 1.
12h - 5 = 11h + 5 - h
2h = 10
h = 5.
-2x = 2
x = - 1.
12h - 5 = 11h + 5 - h
2h = 10
h = 5.

3x-5x+8-8=5x-5x+10-8
-2x=-2
-2x/-2=-2/-2
x=1
12h-5=10h+5
12h-10h-5+5=10h-10h+5+5
2h=10
h=5
-2x=-2
-2x/-2=-2/-2
x=1
12h-5=10h+5
12h-10h-5+5=10h-10h+5+5
2h=10
h=5

question 1
3x + 8 = 5x + 10
=3x - 5x= 10 - 8
= -2x = 2
= x = 2/-2
= x = -1
question 2
12h - 5 = 11h + 5 - h
=12h - 11h + h = 5 + 5
=2h = 10
=h =10/2
=h = 5
3x + 8 = 5x + 10
=3x - 5x= 10 - 8
= -2x = 2
= x = 2/-2
= x = -1
question 2
12h - 5 = 11h + 5 - h
=12h - 11h + h = 5 + 5
=2h = 10
=h =10/2
=h = 5

Question 1
- 8 = 2x
x = - 4
Question 2
12 h - 5 = 10 h + 5
2h = 10
h = 5
- 8 = 2x
x = - 4
Question 2
12 h - 5 = 10 h + 5
2h = 10
h = 5

-3x to other side
-10 to other side
-2/2 = -1
dont feel like doin other one...
-10 to other side
-2/2 = -1
dont feel like doin other one...

1st one
move 3x and 8 to the other side of the equation
0=5x+10-3x-8
0=2x+2
2x=-2 x=-1
2nd one
move all h to the left side and -5 to the right
12h-11h+h=5+5=10
2h=10
h=5
move 3x and 8 to the other side of the equation
0=5x+10-3x-8
0=2x+2
2x=-2 x=-1
2nd one
move all h to the left side and -5 to the right
12h-11h+h=5+5=10
2h=10
h=5
