✔ 最佳答案
Solution: To do this problem, we need to get all the x's to one side and all the constants to another.6x - 8 + 2x - 5 = 7 - 2x
6x + 2x + 2x = 7 + 8 + 5
10x = 20
x = 2
You can check, too!
6*2 - 8 + 2*2 - 5 = 7 - 2*2
12 - 8 + 4 - 5 = 7 - 4
4 - 1 = 3
3 = 3

6x-8+2x-5=7-2x
add 2x both sides and collect terms
10x -13 = 7
add 13 to both
10x = 20
x=2
add 2x both sides and collect terms
10x -13 = 7
add 13 to both
10x = 20
x=2

8 x - 13 = 7 - 2 x
10 x = 20
x = 2
10 x = 20
x = 2

6x - 8 + 2x - 5 = 7 - 2x
6x + 2x - 8 - 5 = 7 - 2x
8x - 13 = 7 - 2x
8x + 2x = 7 + 13
10x = 20
x = 20/10
x = 2
6x + 2x - 8 - 5 = 7 - 2x
8x - 13 = 7 - 2x
8x + 2x = 7 + 13
10x = 20
x = 20/10
x = 2

Combine like terms
8x - 13 = 7 - 2x
Add 2x to both sides
10x - 13 = 7
Add 13 to both sides
10x = 20
Divide both sides by 10
x = 2
8x - 13 = 7 - 2x
Add 2x to both sides
10x - 13 = 7
Add 13 to both sides
10x = 20
Divide both sides by 10
x = 2

collect all variables to one side and constants to the other side
6x+2x+2x=7+8+5
10x=20
x=2
6x+2x+2x=7+8+5
10x=20
x=2

6x-8+2x-5=7-2x
ad 6x+2x = 8x
-8+-5= =13
8x-13=7-2x
get your x's on one side and the numbers on the other.. so
8x+2x = 10x
7+13 = 20
10x=20
20 divided by 10 is 2
x=2
ad 6x+2x = 8x
-8+-5= =13
8x-13=7-2x
get your x's on one side and the numbers on the other.. so
8x+2x = 10x
7+13 = 20
10x=20

6x - 8 + 2x - 5 = 7 - 2x.....Add 2x, 8 and 5 to both sides
6x + 2x + 2x = 7+ 8 + 5
10x = 20
x = 2
6x + 2x + 2x = 7+ 8 + 5
10x = 20
x = 2
